Learning science encompasses much more than simply memorizing facts.
It requires working the end-of-chapter/section exercises.
Student's main goal should not be to simply get the correct answer but to understand the process of getting the answer.
Memorizing the solutions for specific problems is not a very good way to prepare for an exam.
Truly educated people use their knowledge as a starting point - a base
for creative approaches to solving problems.
Be
patient and thoughtful and work hard to understand rather than simply memorize. Have an interesting and satisfying year!
