Agree with this. Without a diagnostic you won't know whether you should do October, November, or January. But I will say that most people need more than 3 months. https://7sage.com/the-three-worst-lsat-mistakes/
Don't rush a test like the LSAT. It's one of the major components of your law school application and it's not good for your headspace. Come back with a score (maybe it's really good!) and we can help you more. The kind of score band you would need also depends on what your GPA is (cGPA, L2, B2). Of course the better the LSAT score the better but if you've got an amazing GPA then that at least gives you more room to breathe.
One thing to note about disclosed vs. not disclosed. If Flex ends up continuing, there's a good chance that a disclosed administration might end up becoming non-disclosed. And I would bet that Flex continues through until at least the end of this year, with how COVID is still messing around with everything.
The average GPA was 3.7 / 4.33 (L20) and The average LSAT is 160. With no ECs / work experience you will have a long shot.
I suggest you apply to SasK as well.
Once you get 160+ a lot of doors will open for you (Alberta, Calgary, Manitoba, UNB, DAL, etc).
