Hi everyone,
I am really not sure how to relay my situation but I'll try my best. I am sorry in advanced if it seems all over the place. So here is a general background (can I even call it that)? of my situation: I was fortunate enough to be able to spend extensive time studying for the LSAT since last summer 2016. I should have used my time WISELY. Instead, I continued to procrastinate and push back studying for the LSAT. I had a lot of time and because of this, I kept telling myself not to worry; however, the few days that I DID study for the LSAT (which was usually two or three times a week for about 30 mins to an hour) I did not put my full effort in either. I purchased the Powerscore LG and LR books and essentially rushed them for the past year. After finishing them this summer 2017, I began taking PTs untimed. My scores started to increase up to mid 160s untimed after a few. Similar to reading the Powerscore books (two or three times a week), I only did the untimed PTs once or twice a week with several breaks (yes, I know. Terrible). Throughout this period, however, I frequently consulted LSAT discussion boards such as this, TLS, and the reddit forum.
My current situation:
I am currently registered for the September 2017 test (which is about a week away now). I started taking my FIRST timed PTs for about a week now and my scores are continuing to stay in the low 150s. I also made the mistake of not thoroughly reviewing the PTs or using BR. I am pretty sure I will do just as poorly on the test next week as I have on the PTs I am taking. I am not really sure what to do... Do you recommend I start from learning the fundamentals properly? I was considering using the 7sage course to study for the LSAT. Even if I did bomb this September test next week I am signing up for December to retake it with much better study habits because I have learned (the hard way) that there really are no shortcuts to this test.
What I have been hoping for is my GPA (cGPA of 3.90) to compensate for the low LSAT score in this September test since I am applying this cycle and thinking I am a splitter. I am a Canadian applicant and have hopes of getting into either Osgoode or U of T. What are your thoughts/advice/opinions? I know my approach was really, really bad and I will likely get criticized for it but I chose to ask this question in the 7sage forum instead of TLS and the Reddit forum because having I find the help here to be much better and I feel the sense of community is much stronger here.
Thank you for taking the time to read my lengthy post. Apologies again!
