Do the Manhattan Study Guides. Do them twice if you need confidence. Take notes on everything you did not know before. Do every question in the OG twice. Time yourself during the last week (to apply the strategies in the Manhattan Study Guides). The advanced parts in the Manhattan study guides are always useful. Try to understand everything. Don’t just apply stuff, understand why you apply it.

Be open minded to every suggestion. Some small tricks let you solve some geometry GMAT questions within 20 seconds.As I love to give examples, consider this one below.

Assume that p is 16 and q is 9. What is the area of perpendicular triangle ABC (see diagram below)?I tried to solve this question by myself for twenty minutes until I saw that triangle SBC is equal to triangle ABC and that you could equal some things to find out the height. Typical thinking that MGMAT teaches you.

I gave this problem to my dad: He solved it in 15 seconds. He told me that there is actually a rule that for every perpendicular triangle p*q=h², with h being the height (and I checked on the internet, he is right on that one). 9*16 = 144, so the height is 12. 12*25/2 (hypotenuse times height divided by two - triangle area formula) gives you the area (150) within twenty seconds. Nothing that MGMAT or

Kaplan or any study guide would teach you. This is what I mean by "stay open-minded". Especially for geometry and also combinatorics there are tons of simple rules and shortcuts like these. If you still have them take a look at your highschool mathbooks. Those often contain stuff like this.

Thanks for sharing the geometry tip and your story!
