DegreeOS vs InstantCert vs Study.com vs Modern States (2026)

Finishers researching credit-by-exam usually bump into the same four names — DegreeOS, InstantCert, Study.com, and Modern States. They all touch the same space, but they solve different problems. We are not going to pretend we are the right tool for everyone, so here is an honest read.

Modern States

Modern States is a nonprofit offering free CLEP prep courses and, for many students, a voucher that covers the CLEP exam fee. It is excellent for the very first exam or two when you are testing the waters. The tradeoff is that the content is video-course-heavy and not tied to a personalized degree plan.

InstantCert

InstantCert has been around for decades and specializes in CLEP and DSST flashcard-style study. It has a loyal user base and solid community forums. The content skews toward memorization drills, and the experience is relatively static — same decks for everyone, regardless of what degree you are pursuing.

Study.com

Study.com offers video courses that can earn ACE-recommended college credit, plus CLEP prep. It is more of a course marketplace than a degree-planning platform. Monthly subscription model. Works well if you prefer video instruction and want some self-paced courses mixed in with exams.

DegreeOS

We are the only platform that plans the whole credential graph. Every study session simultaneously maps to your degree progress AND to certifications you could earn next — AWS, CompTIA, HubSpot, NCLEX, FINRA, and 50+ more. Our advisor Merit learns your study patterns and sequences exams to your actual school and degree. The positioning we hold to is simple — we are the only credential platform that learns you.

Which should you pick?

If you want free CLEP prep for one or two exams, use Modern States. If you want classic flashcard drilling, InstantCert. If you want video courses plus exams, Study.com. If you want a personalized roadmap from where you are to a finished degree plus marketable certifications, that is us.
