don't time yourself yet. get a solid grasp of HOW to set up the game - most games are very similar in terms of logic (you'll either have a list or a chart, for example.) Dedicate yourself to the types of logic presented, and work through past lsat's this way. don't even think about time - if you want, try and pace yourself (don't spend an hour on a question, obviously) but don't get caught up in finsihing a section in even 40 minutes yet. once you have an idea of the variance of the games, work on consistency FIRST, THEN time...this might not be until september.
just remember to diagram out the spaces for each variable in the game before looking at the rules for the game. visualize the situation before you approach how the variables work with each other. i've learned the best way to approach games is work from most general to specific. i did a diagnositc last night, doing this consciously (sp?) for the first time last night, and only got one wrong. (it was from the next 10, first one in the book)
good luck, pm me if you want help.
