I generally start with one diagnostic test or if someone have already practiced few mock test then I better ask their score, the topics and the type of questions they committed mistakes or faced difficulty on a recurring basis.This help me identifying the problematic topic /type of questions so that we can focus more on those topics. Also we provide content & practice questions for each topic which have already been asked or at par with the relevant prep exam. After all for scoring high at GMAT/CAT /GRE & SAT one need not to be master at subject but to master the techniques/tricks to solve question and that too in a limited time. GMAT/CAT /GRE & SAT exam generally do not deviate much from the set trend and pattern. Also there are few topics which covers a good weight of the exam so understanding and practicing these questions well is very critical for scoring high at these exams. This is a general strategy which I adopt but the planning of the classes very much depends upon the candidate's weakness, strength and critical areas. Moreover, we look into the individual mock test scores or their actual scores if they have already written these exams once, to devise strategy specific to them for maximum improvement..
