My diagnostic about a month ago was 148, and since then I've been learning, doing drills (untimed) and really trying to understand all the questions and question structures. I did my first PT a month later and got a 146, which was worse than my diagnostic. I am honestly feeling very discouraged and I don't know whether the issue is the time pressure, disassociation, or my abilities. I felt like I guessed a lot because I was running out of time, but I also did not really try as much as I should have. I'm registered for the September LSAT but now i don't know if I'll be able to improve significantly by then.

Is this normal for your first practice test after learning? Should I be doing practice tests or timed sections more often?

Any advice would be greatly appreciated.
