Plan a challenging, but workable course schedule. Consult your academic advisor to plan a schedule that will allow you to have the most success.
Enroll in the appropriate classes per year. Depending on if you've planned a 4, 5 or 6-year plan, you will have to take certain courses. Essential coursework includes statistics, physics, molecular chemistry, organic chemistry and organic biology. You will take all of these in conjunction with lab courses so that you can practice what you learn in lecture classes.
Earn As in class. Listen to instructors. Practice research. Use study groups. Lower grades do not look good on medical school applications. While the MCAT is highly relevant, the grades show progress and work ethic through coursework.
Manage your time well. Mix classroom time with lab time and studying. Allow time for socialization as well.
Rest your mind and body. Avoid burnout and fatigue. Take days off. When not in class or studying, take time to rest. Nap between classes during the week. Your brain will not function at its highest capacity without rest and sleep.
