Reviewing online learning platforms since 2019. Review methodology
THE SHORT ANSWER
Bottom line: the real advantages of online courses are control over your time, lower cost for job skills, a far wider choice, and being able to keep working while you learn. Two popular claims do not hold up: online learners are less likely to finish, not more, and a certificate rarely replaces a degree on its own. The advantages go to people who choose a course for a specific outcome and plan their study time.
- Flexibility: study when and where you can, without a commute.
- Cost: about $120–$468 a year for a subscription library on the platforms we track, and a lot of free vendor training.
- Choice: universities, companies and practitioners you could never reach locally.
- Watch out for: finishing. Plan your study time before you enrol.

The advantages depend on the format, so it helps to separate three kinds of course. Self-paced courses (most of Udemy, Coursera, LinkedIn Learning and vendor training) give you recorded lessons and quizzes to work through on your own schedule. Cohort courses add a start date, weekly deadlines and a group, sometimes with live sessions. Online degrees and certificates from universities carry academic credit and usually cost far more. Most of the benefits below apply to all three; where one applies mainly to self-paced learning, we say so.
1. You set the schedule
Self-paced courses have no timetable. You can study at 6 a.m. before work, on a lunch break or over a weekend, and a week of illness or travel does not make you miss a lecture you cannot get back. Cohort courses are less flexible but still let you watch recorded material at any time inside a weekly window.
The same freedom is also the main risk. When nothing forces you to show up, it is easy not to. Book fixed study sessions in your calendar before you start; our online study tips explain the planning habits with the best research behind them.
2. No commute and no move
Learning online removes travel time and travel cost, and for many people it removes the bigger barrier: moving to where the course is taught. You can take a university course from another country, or train with a company in another city, without relocating, leaving family or giving up a lease. For carers, people in rural areas and people with disabilities that make travel hard, this is often the difference between studying and not studying at all.
3. Job skills cost far less
If your goal is a skill rather than a degree, online learning is much cheaper than the classroom. Annual subscriptions on the platforms we track run from about $120 to $468 a year for an entire library (see our online learning statistics for the price table), and single courses on marketplaces such as Udemy are frequently discounted. A great deal of high-quality training is free: AWS, Microsoft and Google all publish free learning paths for their own technologies, and our guide to Microsoft’s free training shows how far that goes.
Online degrees are the exception. Some universities charge online students the same per-credit tuition as on-campus students, so the saving is the commute and the relocation, not the tuition. Compare the per-credit price, not the label.
4. You can pause, rewind and speed up
A recorded lesson can be replayed until it makes sense, paused while you try an exercise, and watched faster when the material is familiar. Speed-watching is less risky than it sounds: in a 2021 study in Applied Cognitive Psychology, raising lecture video speed from 1x to 1.5x or 2x cost learners very little comprehension, both immediately and a week later, although performance fell beyond 2x (Murphy et al., 2021). The researchers suggest spending the time saved on extra study or a second viewing close to the exam.
5. You keep your job and your income
Going back to a classroom often means cutting hours or leaving work. An online course fits around a job, so you keep earning while you learn, and you can apply new skills at work the following week. That matters more each year: employers surveyed for the World Economic Forum’s Future of Jobs Report 2025 expect 39% of the key skills required in the job market to change by 2030 (World Economic Forum). For most people, keeping up will mean learning alongside a job rather than stopping work to study.
6. Far more choice of subject and teacher
A local college offers the courses it has staff and enrolment for. Online, you can choose between thousands of courses from universities, companies and working practitioners, including niche subjects no nearby school teaches. You can also choose the teacher: preview lessons and reviews let you check an instructor’s style before you commit, which is impossible when a class is assigned to whoever is teaching that term. Our guide to the best online learning platforms compares where each kind of course lives.
7. You can try a course before paying
Most platforms let you look inside first. Coursera lets you preview the first module of nearly every course for free; it replaced its old free “audit” option with this preview in August 2025 (Coursera). edX still offers a free audit track on many courses, Udemy shows preview lessons and the full curriculum, and refund windows typically run from 7 to 30 days depending on the platform. A classroom course rarely lets you sit in on the first week and then walk away with your money.
8. Training written by the people who set the standard
For many technical fields, the most authoritative training is online because the companies that own the technology publish it there. Cloud providers write the courses for their own certification exams, software companies document their tools in free learning paths, and many online instructors teach what they do for a living. That keeps content closer to current practice than a textbook revised every few years. Check the last-updated date on anything technical: a course that has not been touched in two years may teach an old version.
9. A credential you can show
Online courses can end in something an employer recognises: a vendor certification, a professional certificate from a well-known company or university, or academic credit. Learners report real gains. In Coursera’s 2025 Learner Outcomes Report, a survey of more than 52,000 learners in 179 countries conducted with The Harris Poll, 91% said they achieved at least one positive career outcome after completing a course and 46% reported a salary increase (Coursera, October 2025). Those are self-reported figures from people who finished, published by the platform itself, so read them as an upper bound rather than a typical result.

10. You practise learning on your own
Finishing a self-paced course means planning your time, finding answers when you are stuck and holding yourself to deadlines no one else sets. Those are the same habits you need to keep learning after any course ends, which, given how quickly job skills are changing, is most of a working life. It is also a skill you can point to: a finished project from a self-directed course shows an employer that you can learn something new without being taught it in a room.
Two advantages that do not hold up
CORRECTION, SEPTEMBER 2026
An earlier version of this page said online learners are more likely to complete their courses than classroom students, citing an 85% completion rate from a 2014 Harvard pilot. That pilot was a small, paid Harvard Business School program, and it does not describe online courses in general. The research below shows the opposite, and we have removed the claim.
Myth 1: online learners are more likely to finish
Completion is the weak spot of online learning. A 2019 analysis in Science by Justin Reich and José Ruipérez-Valiente found that only 3.13% of all participants in MIT and Harvard edX courses completed in 2017–18. Among learners who had paid for a verified certificate, 46% completed (Inside Higher Ed summary). Light-touch fixes do not close the gap on their own: in a study of about a quarter of a million students across 247 Harvard, MIT and Stanford online courses, self-regulation exercises such as planning prompts raised engagement in the first few weeks but not final completion rates (Kizilcec et al., PNAS, 2020).
The lesson is not that online learning fails; it is that finishing depends on commitment and structure you have to build yourself. Paying, working to deadlines, and knowing exactly why you enrolled all move the odds.
Myth 2: a certificate replaces a degree
Many employers say they have dropped degree requirements. Far fewer have changed who they hire. Research from Harvard Business School and the Burning Glass Institute found that fewer than 1 in 700 hires in 2023 reflected dropped degree requirements (Harvard Business School, 2025). An online certificate helps most when it adds to a degree or work experience, or when it is an industry certification the job actually asks for.
Mixed: “fewer distractions”
Studying at home removes classroom chatter but adds your phone, your inbox and every other tab. Multitasking is costly: in an experiment published in Computers & Education, students who multitasked on a laptop during a lecture scored lower on a test, and so did students who could simply see a multitasking classmate (Sana, Weston and Cepeda, 2013). Online learning only has fewer distractions if you set up your study time that way.

Who gets the most from online courses
| You are… | The biggest advantage | Watch out for |
|---|---|---|
| Working full time and adding a skill | Learning around your job | Skipping weeks; book fixed sessions |
| Changing career | Low-cost way to test a field before a big program | Collecting certificates without building projects |
| Preparing for a certification exam | Training written against the official exam guide | Courses built for an older exam version |
| Living far from a good college | Access to courses you could not reach | Unreliable internet; download lessons offline |
| Someone who needs structure to stay motivated | Cohort courses with deadlines and a group | Purely self-paced courses with no deadlines |
If you are weighing up whether to spend money at all, our analysis of whether online courses are worth it sets the pros against the cons and gives a verdict, and our paid vs free courses comparison shows what the price usually buys.
How to actually get these advantages
- Name the outcome. A job, a certification, a skill for your current role, or interest. It decides which course and credential make sense.
- Pick a format that fits how you work. If you have abandoned self-paced courses before, choose one with deadlines and a group.
- Preview before paying. Watch the first lesson, read recent reviews and check the refund window.
- Book your study time. Put two or three fixed sessions a week in your calendar before the course starts.
- Study actively. Quiz yourself, do the exercises and build the project; watching alone is not learning.
Our checklist on how to choose an online course covers the first three steps in detail, and the online study tips cover the last two.
Frequently asked questions
What are the main advantages of online courses?
The advantages that hold up are control over your schedule, no commute or relocation, lower cost for job skills, the ability to pause, rewind and speed up lessons, keeping your job while you learn, a far wider choice of subjects and teachers, the option to try a course before paying, and content written by the companies that set industry standards. A recognised credential can also help your career, though rarely on its own.
Are online courses easier to finish than classroom courses?
No. Completion is the weak spot of online learning. A 2019 study in Science found that only 3.13% of all participants in MIT and Harvard edX courses completed in 2017-18, although 46% of learners who paid for a verified certificate did. Deadlines, payment and a clear reason for enrolling make a large difference.
Are online courses cheaper than college?
For learning a job skill, usually yes: annual subscriptions on the platforms we track run from about $120 to $468 a year, and many vendors publish free training. Online degrees are a different case. Some universities charge online students the same per-credit tuition as on-campus students, so compare the per-credit price rather than assuming online is cheaper.
Do employers value online course certificates?
Some more than others. Vendor certifications such as AWS or Microsoft exams and professional certificates from recognised universities or companies carry weight; a completion certificate mainly shows you finished. Treat a certificate as supporting evidence and pair it with projects you can show. Research from Harvard Business School and the Burning Glass Institute found that dropped degree requirements changed fewer than 1 in 700 hires in 2023.
What is the biggest disadvantage of online courses?
Staying with the course. With no classroom, timetable or classmates to keep you going, most people who start a free online course stop. The fix is structural: pick a course with deadlines or graded work, book fixed study times in your calendar, and use the study habits with the strongest research behind them.
Can you try an online course before paying?
Usually. Coursera lets you preview the first module of nearly every course for free; it replaced free auditing with this preview in August 2025. edX still offers a free audit track on many courses, Udemy courses show preview lessons, and most platforms have a refund window of 7 to 30 days. Read the terms on the day you buy.
Who benefits most from online courses?
People with a specific goal and limited time: working adults changing roles or adding a skill, people preparing for an industry certification, and anyone without a good local option. People who need a set timetable and a room full of classmates to stay motivated may do better with a live cohort or an in-person class.
Final verdict
Online courses give you control over your time, access to far more subjects and teachers than any local option, and job skills at a fraction of classroom cost, all without leaving work. What they do not give you is the structure that makes people finish, and a certificate on its own is rarely enough to change a hiring decision. Choose a course for a specific outcome, plan when you will study, and do the work actively, and the advantages are real.
