What should I do if I start falling behind in engineering classes?

First, organize the topics and assignments you do not understand, along with your available study time, and prioritize them by deadline and importance. Consult your instructor, TA, learning support office, or academic advisor early to ask about review methods and whether to continue the course. Relearn the fundamentals and use study groups or other materials. If sleep or health is affected, do not overexert yourself; consider using health or counseling services.
