Test taking should follow Mike Holt's recommendation -
First time through the test, answer all, the easy questions (this could be all of them, but then again, maybe not) on the first time through the test.
Second pass , do the easy look ups.
Third time, now do the crawl for hard to answer questions that you think you can solve.
Fourth pass, don't leave any question blank! If you don't mark something, you will miss it for sure!
I've done Mike's materials and courses for year's, and averaged 85% t0 90+ % for scores. So I can conclude that Mike put's out some of the best information available (at least for me).
Fianally, remember, the whole mission is to PASS, regardlsess of score, so the more questions answered (correctly) the better the possibility of securing a license in whatever your testing for! Don't bog down on a question! Keep moving!
Even if you do not pass, you'll know what to study for on the next go around, so test whenever possible to get an idea of where you are at.
