Multiple-choice (MC) exam tips

Success on a MC exam requires both subject matter knowledge AND test taking skills.  A student with good test taking skills with average subject matter knowledge could have a significantly higher score than a student with poor test taking skills with good subject matter knowledge, i.e. (unfortunately ?) good test taking skills are valuable. 

To improve MC exam test taking skills:  practice, practice, & practice - using e.g.  AP Chemistry study guides, SAT II Chemistry study guides, & California High School Chemistry exam study guides.

usually, the choices are quite different, so you need to only estimate (gerneric suggestions: site 1, site 2; chem examples) the answer - do not calculate the actual answer - it could be a waste of your time.  also, use factoring.
