Frequently Asked Questions

The Fundamentals of Engineering (FE) exam is the first step to becoming a licensed Professional Engineer (PE). It is a 110-question, 6-hour computer-based test administered by NCEES. Passing the FE exam earns you the Engineer in Training (EIT) designation.

CrushFE uses AI-powered flashcards with spaced repetition to help you study efficiently. You study flashcards organized by NCEES exam topics, rate your confidence, and our algorithm schedules optimal review times. An AI tutor is available to explain concepts in different ways.

Spaced repetition is a scientifically proven study technique that schedules reviews at increasing intervals. Cards you know well are shown less frequently, while cards you struggle with are shown more often. This optimizes your study time and improves long-term retention.

After studying a flashcard, you can ask the AI tutor to explain the concept differently, explain why a specific wrong answer is wrong, generate similar practice problems, or have a multi-turn conversation about the topic. The AI is powered by advanced language models optimized for engineering and math.
