Warning: looking up the answers before actually going through the problems, solving them and writing down your answers is a waste of time. Never check the correct answer before writing down your answer.
Do not use the textbook for practice exams. If you need, close the exam, read the textbook, then close it and return to the exam. Otherwise it is a waste of time.
