If you are trying to finish a degree for less money and in less time, you have probably come across the same four names again and again: Sophia Learning, Study.com, StraighterLine and Saylor Academy. All four offer self-paced online courses that many colleges accept for transfer credit. But they are not interchangeable, and the "best" one depends on your university, your degree and how you like to study.
This guide compares them on the things that matter: how courses work, what they cost, how exams are run, how credit reaches your school and which students each one suits.
The most important rule first. No provider can promise that a course will count toward your degree. Only your college decides that. Before you enroll in anything, confirm how your school treats the course. Our credit-transfer service does that checking for you.
How alternative-credit providers work
All four providers sit outside the traditional college system. You don't enroll in a degree with them (in most cases). You take individual courses, pass them, and then send a transcript to the college that will award your degree.
Most of their courses have been reviewed by one or both of the two main credit-recommendation organizations:
- ACE Learning Evaluations (American Council on Education)
- NCCRS (National College Credit Recommendation Service)
These organizations look at a course and recommend how many college credits it is worth and at what level. Many colleges accept those recommendations. Others accept courses only through direct partnership agreements with the provider. Some accept neither. You can read more in our guide to ACE and NCCRS credit recommendations.

Sophia Learning
How it works. Sophia sells a monthly membership. Within your membership you can work through courses at your own pace, usually with a limit on how many you take at the same time. Courses are built from short lessons, practice "challenges", and graded assessments called milestones, plus written or project-style "touchstones" in many courses.
Strengths.
- Low cost if you work steadily. A student who completes several courses in a month pays far less per credit than at a traditional college.
- Clear structure. Each course shows exactly what is left.
- A large list of partner colleges that publish how they accept Sophia courses.
Limitations.
- The catalog leans toward general education and introductory courses. Most Sophia courses are lower-division.
- If your school is not a partner and does not accept ACE credit, Sophia credit may not help you at all.
Best for: students who need to clear general education requirements quickly at a school that already accepts Sophia. See our Sophia transfer guide and our Sophia course-support page.
Study.com
How it works. Study.com combines short video lessons with quizzes and a proctored final exam for each credit course. Many courses also include a written assignment. Exams are taken online with webcam proctoring.
Strengths.
- The widest catalog of the four, including a meaningful number of upper-division courses (useful because many bachelor's degrees require a minimum number of upper-level credits).
- Courses are reviewed by both ACE and NCCRS, which helps at colleges that accept one but not the other.
- Video-led teaching works well for students who learn by watching.
Limitations.
- Membership pricing has changed recently, and limits on how many courses you can take per month vary by plan.
- Proctored finals have strict rules about your room, your screen and your identity checks. Read them before exam day.
Best for: students who need upper-level credit or courses outside general education. Read our Study.com transfer guide and see Study.com course support.
StraighterLine
How it works. StraighterLine charges a monthly membership plus a fee for each course you start. Courses include graded quizzes, written assignments in some subjects and a proctored final exam. Science courses can include virtual or at-home lab components.
Strengths.
- A large network of partner colleges, many with published transfer guarantees for specific courses.
- Strong in nursing and health-science prerequisites: anatomy and physiology, microbiology, chemistry, statistics. This makes it popular with pre-nursing students.
- Access to tutoring within the platform for many courses.
Limitations.
- The per-course fee means the cost per credit is usually higher than Sophia.
- Lab-science courses take longer and cost more.
Best for: nursing and allied-health students who need prerequisites, and students whose college is a StraighterLine partner. Read our StraighterLine transfer guide and see StraighterLine course support.
Saylor Academy
How it works. Saylor Academy is a nonprofit. Its course materials are free. A smaller set of courses, sometimes called "Saylor Direct Credit" courses, has a proctored final exam that, once passed, carries an ACE or NCCRS credit recommendation. There is a small proctoring fee for those exams.
Strengths.
- By far the cheapest route to credit.
- Good for motivated, independent learners who are comfortable reading open textbooks.
Limitations.
- Only some courses carry a credit recommendation, so check before you study.
- Less hand-holding: there is no instructor, and materials vary in style.
Best for: budget-conscious students who are disciplined self-learners. Read our Saylor Academy guide and see Saylor course support.
How to choose: five questions to ask
1. What does my college actually accept?
This is the deciding factor, and it overrides everything else in this article. Look for:
- Your school's transfer credit policy (usually in the academic catalog).
- Whether your school is listed as a partner on the provider's website.
- Whether your school accepts ACE or NCCRS credit recommendations.
- Any limit on how much alternative credit you can use.
2. Which requirements do I still need?
Get your degree audit (sometimes called a degree evaluation or academic progress report) from your school's student portal or advisor. Courses only save you money if they fill a requirement you still have. Our guide on how many credits you can transfer explains how to read an audit.
3. Do I need lower-level or upper-level credit?
Many bachelor's degrees require 30 to 45 upper-division credits. Sophia and StraighterLine are mostly lower-division. Study.com has more upper-division options.
4. How do I learn best?
- Short videos: Study.com.
- Structured written lessons with frequent checks: Sophia.
- Traditional course structure, including labs: StraighterLine.
- Reading and self-direction: Saylor.
5. What is my real budget, including time?
A monthly membership is only cheap if you finish courses. Work out how many hours a week you can study, how many courses that realistically means per month, and divide the total cost by the credits you will actually earn.
Can I combine providers?
Yes, and many students do. A common pattern is to take general education courses at the cheapest provider your school accepts, and use another provider for the specific courses the first one doesn't offer. The risk is duplication: two courses that look different may count as the same requirement, and your school will only award credit once. Map every course against your requirements before enrolling.
Common mistakes to avoid
- Enrolling before checking. The most expensive course is one your school won't accept.
- Ignoring residency rules. Most colleges require a minimum number of credits to be earned at the college itself. Alternative credit can't replace those.
- Assuming "accepted" means "applies to my degree." A course can transfer as a general elective rather than filling the requirement you wanted.
- Letting memberships run while you're busy. Pause or cancel when you're not studying.
- Forgetting transcript fees and timing. Sending transcripts can take weeks. Leave time before registration or graduation deadlines.
Frequently asked questions
Which provider is the cheapest?
Saylor Academy is usually the cheapest because its courses are free, with a small fee only for proctored exams. Among the membership providers, the cheapest one is whichever lets you complete the most accepted credits per month. Check current prices on each provider's official site.
Are these providers accredited?
They are generally not accredited colleges themselves. Their courses are evaluated by ACE or NCCRS, which recommend credit. Your accredited college then decides whether to award credit.
Will my credits expire?
Credit recommendations are tied to the date you completed the course and the evaluation in force then. Most colleges don't set an expiry on general education credit, but some programs (especially sciences and nursing) require prerequisites to be recent. Check your program's rules.
Can someone else complete my course for me?
No. Each provider requires you to do your own work, and proctored exams verify your identity. We help with planning, tutoring and study support only. See our academic integrity policy.
