"There is lots of information that has been crammed into heads for tests that have not survived the test of time!"
This is so so so true (times infinity!). I can’t tell you how many times I have memorized and memorized and gotten an A on the test; then a week later, I have trouble remembering anything but the simplest of facts. College is just so fast paced and you will always have something new to learn and study.
My advice
