Ace Your FE Exam (For Free)
Passing the Fundamentals of Engineering exam is the first big milestone in your engineering career, and reef.science gives you everything you need to get there without spending a single dime. Free practice problems, free explanations, free course review. We built this because we think exam prep should be accessible to everyone, not locked behind a $200 paywall.

What you get
Think of reef.science as your study partner who never gets tired and always shows their work. Here is what we bring to the table, completely free of charge.
Unlimited practice questions
Every problem is generated fresh from parameterized templates. You will never run out of new questions to solve, and you will never see the same numbers twice.
Detailed explanations
Every single answer includes a full walkthrough of the solution, common mistakes to avoid, and the underlying concept review. No "the answer is B" nonsense here.
Full course review
Our courses cover the complete university curriculum, not just the topics that show up on the FE. Use them to brush up on fundamentals or learn something new.
Interactive diagrams
Circuit schematics, beam loading diagrams, P-v plots, and free body diagrams render alongside problems so you can visualize what you are solving.
Courses mapped to the FE
The FE exam covers seven core engineering disciplines, and we have practice generators and course content for all of them. Statics, dynamics, thermodynamics, fluid mechanics, mechanics of materials, circuits, and engineering economics are all represented in our question bank. Each discipline maps directly to the NCEES specification so you know you are studying the right material. We also cover math foundations, physics, and chemistry for the general section of the exam.

How practice works
No account walls, no trial limits, no "upgrade to see the answer." You click, you practice, you learn. That is the whole workflow.
Pick a topic
Filter by course and difficulty. Start with the subjects you feel shakiest on, or go broad and test yourself across all ten disciplines.
Solve unlimited problems
Each click generates a brand new question with fresh values. Practice until the patterns feel automatic and the formulas live in your muscle memory.
Review the explanations
Read through the step-by-step solution, study the concept review, and check the FE Exam tips that highlight what the real test emphasizes.
We're always growing
Reef.science is actively being developed, and we are adding new question generators, courses, and features on a regular basis. Right now we have 248 generators across ten courses, but that number goes up every week. We recently added circuit diagrams to every electrical engineering problem, P-v plots to thermodynamics questions, and a streak system to keep you motivated.
We know some things are still rough around the edges, and we appreciate you bearing with us while we build. If you spot a mistake in a problem, notice a missing topic, or just have an idea for something that would help you study, we genuinely want to hear about it. Hit the feedback button on any page and tell us what you think.
Did we mention it's free?
No premium tier. No "freemium" bait-and-switch. No ads cluttering your study session. Reef.science is free because we believe that access to high-quality STEM education should not depend on your bank account. Your tuition is already expensive enough, and your exam prep tools should not add to the pile.
Education should be free, fun, and fantastic (the three most important F words).
