Good at the questions, but too slow for the time alotted.

Hi, so I took the first practice LSAT in the course (June 2007). I found that I'm very, very good at finding the right answers, but it takes me longer than 35 minutes. I was wondering if anyone else has been having this problem? When I don't try to answer everything in 35 minutes, I get only a few wrong. It's frustrating because the explanations to each answer make total sense to me, but I missed the question because i had to start rushing through my thought process in order to fit them in 35 minutes.
