Hi Sara,
Thanks for your question.
Selecting the easiest LG to complete first provides a significant advantage, since each question is worth exactly one point. Such a game is supposed to take less time to complete, which gives you both the time and the confidence to tackle another game. So, choosing the easiest game to start with is basically a no-brainer. The question is, how do you know which game is the easiest?
Typically, the first game in your section will be below-average in difficulty. Often it is actually the easiest game, so you should consider that game first. It is also important to know the factors that typically increase the difficulty of any particular game: rules that employ conditional reasoning; numerical distributions (look for keywords such as "at least," "at most"); a large number of variables and/or variable sets. If you see any one of these elements in a game, you can be sure that the game will not be the easiest game in your section.
You also probably know the types of games that you yourself perform the best and worst on. Maybe you find Basic Linear games to be easier than Grouping? Or perhaps prefer Defined to Undefined Grouping games? Either way, after months of test prep you should be able to identify your strengths and weaknesses in Logic Games and capitalize on your strengths.
With Reading Comp., choose the passage whose topic you find most appealing (as in interesting, familiar, or potentially easier to understand). Granted, topic doesn't matter
per se, as you will be given all the information you need in order to answer every question. That said, people typically show higher levels of engagement with passages whose topics they find fascinating, and as a result perform better on the questions. Also, make sure you don't get "stuck" on any particular question: if you can't easily prove the answer, your time is better spent answering another question.
All else being equal, the number of questions per passage (or game) matters too. If I had only one game or one passage to do, and cannot decide which one would be the easiest, I'd choose the one with the most questions in it. More bang for your buck, so to speak.
One last thing I wanted to mention (which is slightly off-topic, but relevant to you). I read in another post that you have been denied accommodated testing for ADHD. The LSAC has notoriously stringent requirements for granting such accommodations: a note from a psychiatrist or an attending physician won't cut it. Typically, you need to sit through several days of cognitive assessment tests and provide extensive evidence of disability. In New York City (and Chicago), there is a Center for Cognitive Assessment (
http://cognitive-assessment.com/) that could be helpful, if you decide to go down that route. Your health insurance may or may not cover their services, but it's probably worth a try.
Good luck!
