Here are five tips/advice/personal learnings to help you on your NMAT test:
1. You don't really have to enroll in a review center. It all boils down on one thing: if you have the money, go enroll, but if you don't, then you don't have to. If you are like me who still relies on her parents' financial support, do your parents a favor and don't unload 5,000 pesos for a week's worth of review. It doesn't guarantee you anything anyway. A review center cannot feed you everything, studying on your own is still essential.
2. Answer the practice test. When I was reviewing for the NMAT, the one thing I usually asked is if the practice test is any similar with the exam given. And after taking the exam, I realize that it certainly is. The topics covered on the practice tests are the same ones given during the actual exam. Definitely read on the concepts on the practice test.
3. Study High School books. If I could be thankful for anything, that would be my brother's fourth year HS books. Believe me, if anything should cover for the Physics or Chem part, that would be reading HS stuff. You don't have to study mind contorting topics, just the basics.
3. The internet is your friend. One thing that really helped me is reading on forums about how people tackled the exam. I learned techniques which certainly helped me a lot. For the number/letter series, write the alphabet several times on the scratch sheet and draw a skipping line to determine the pattern. It is easier seeing the pattern visually rather than counting manually.
4. Interview people who have taken the test before. Nothing beats actually sitting down on the exam venue. Talk to people who have taken the exam before, and have them tell you what is it actually like.
5. Last and most importantly, pray. Surely God is more powerful than any exam you would take.
