Hi Classof15USA,
While most questions on the GMAT can be solved in more than one way, there are never that many 'options' when it comes to approaching a prompt - so part of your 'analysis' when it comes to any individual GMAT question should be in terms of which of the possible approaches "fits" what the prompt gives you to work with. To that end, if you've trained properly, then every question you see should remind you of something that you already dealt with during your studies. It might be a math/grammar rule, Number Property, phrase, etc., but your ability to draw on that memory/experience should also help you to see how to approach a new prompt (or potentially get 'unstuck' from a prompt). Certain prompts also just require a bit of 'playing around', so you have to take some notes and try to find a pattern that's built into the information.
GMAT assassins aren't born, they're made,
