I'm taking my LSAT this June!!! ARRG!!
I'm a Poli SCi undergrad, in my second year.
Best advice I can offer is STUDY STUDY STUDY!
If you aren't going to take the course, then make it realistic (give yourself 35 per sectionj and go through an entire exam!!
I find this helpfully b/c stamina plays a big role, at least for me. After the first two sections my mind starts wonderiung and it takes practice to evetually be able to focus and concentrate for all four section (plus one experimental).
Also, you might want to eliminate a few questions right off the bat...if you find time is slipping when your studying. For example, you might wnat to only do 20 of the 24 reasoning questions in 35 minutes. And just mark C for the rest. Or omit one logic game or reading comp.
All I know is that I've studied realigiously for this test for the past month and a half and I am still antsy and nervous thinking I only have two months left.
But I think deep down I know I am on my way...
WARNING: Get yourself a guidebook...one with REAL LSAT questions/examples...you'll understand why later...
At first its very discouraging especially the logic games but once you sit down and really start practicing you see patterns and reoccuring themes and then it becomes systematic....
The only real issue is the INSANE time pressure you are under, so you have to simulate that in your practice...
Best of luck....
