Course Structure:
Study.com consists of courses that include hundreds of lessons and quizzes, although these lessons and quizzes became optional in 2025. You just need to complete the chapter tests and final exam to complete the course, which you can do quite fast, while still learning the material. Also they have practice tests to help you prepare for the final exam. The practice tests are optional but recommended to gauge your readiness. All course material is available immediately—work through the content at your own pace and take the final when you're ready.
Taking notes during the readings is highly recommended.
Grading Criteria:
Some courses at Study.com will feature only Chapter Tests and Final Exam. Whereas the Chapter Tests will be 67% of your grade and the Final Exam will be 33% of your grade. If you get 100% on all the Chapter Tests, you'd basically be able to nearly guarantee a passing grade in the class, regardless of your final exam score.

Some other courses are 33% Assignment 33% Chapter Tests and 33% Final Exam.

Grading time on the writing assignments has wildly varied by student feedback, but seems to be more favorable than unfavorable with grades usually coming back in a few days.
User Interface:
Study.com has a modern, clean interface that's easy to navigate. It's one of the better-designed platforms in this space.
Pricing:
Study.com offers two plans:
- $95/month – Unlimited courses, 2 enrolled at a time
- $235/month – Unlimited courses, 3 enrolled at a time, access to all courses.
Is Study.com Proctored?
No. Study.com removed proctoring in 2025. All exams are now unproctored, similar to Sophia.
Average Course Length:
Completion time varies by person. The fastest you can complete a course is a couple of days and they are a relatively fast platform. Most courses probably take 4-7 days each if you are spending at least a few hours a day invested. Upper Level Courses, English Courses, Lab Courses, and Computer Science courses that involve programming may take 10+ days each. These are conservative timelines.

I personally took around 30 credits on Study.com multiple years ago, including most of my Computer Science courses for my TESU Computer Science Degree. I enjoyed my experience on the platform and you likely would as well.
