Uh... its just all about common sense and lessons from highschool. Its easy, for me but it really depends on the school.
If your into technical schools such as TUP, PUP, MAPUA, CIT, and most, always learn your TLE subjects, most of this schools give questions in mechanical and technical comprehension, example questions:

1. give the type of screwdriver needed to screw or unscrew a cross-head screw?
choices: A. Philipps-crosshead screwdriver B. Flat head screwdriver C. Nuthead Driver

2. Convert 5000 kilometers to meters

3. What is the Unit of Electrical Power??

- always remeber to study your, science, TLE and physics subjects in entering these schools!! 

Good Luck on the Academic battlefield!! o7
