What I Have Learned from the Princeton Review’s GRE Study Guide
by thecustomhouse
The Princeton Review can be unexpectedly deep, or perhaps I’m just trying to find something interesting in a study manual (it’s very possible):
1) Look for the wrong answers. Once you’ve eliminated the wrong ones, picking the right one will be easier.
2) Let it go. We all make mistakes.
3) Walk away from difficulty until you are ready. Solve easy problems first.
4) Just because something is hard does not mean it is worth more to you.
5) Bend don’t push.

That is unexpectedly deep. And wow, is #4 on point for me — I tend toward that assumption way too often.
#2 is very important!
