Put in time for all aspects of the LSAT, not just the area that always gives you problems. I remember focusing purely on logic games for the final month before the LSAT because I was always so bad at them and routinely did well on the other sections. That strategy backfired when I aced the logic games section and did weaker than anticipated on the other two sections. To this day, I have chalked that up to narrowing my study focus too much in the weeks leading up to test day. Long story short, work on everything, including the areas you already do well.
As for law school, here's my advice:
(1) Don't just go to any law school you get into. Plenty of terrible schools enrolling students just to generate revenue. Will really hurt you in the end in terms of passing the bar exam and getting a decent job. Not to mention, you'll have a massive amount of debt for an essentially worthless degree.
(2) Go to law school in the area you believe you want to live going forward. While the Uniform Bar Exam is finally making things easier for attorneys to have nationwide options without the hassle of taking multiple bar exams, there is still a regional bias with pretty much every law school outside the T14.
(3) Bust your butt your first year of law school, no matter how difficult it may seem. You'll thank yourself later when you've anchored your GPA in a strong range. While your grades should go up your final two years of law school, it's extremely difficult to prop up a terrible first year GPA, even with stellar grades the remaining two years.
(4) Take real core classes over elective courses during your last two years of school whenever possible. While Business Associations may not seem so interesting when compared to a course like Environmental Law, you'll thank yourself when studying for the bar exam. I know at least two people from my graduating class who finished with bloated GPAs because they avoided every core course they were not required to take and have failed the bar exams at least three times each.
(4) Lastly, studying for the bar exam is going to be the worst summer of your life. No way around it, and I'd bet you would not be able to find someone to tell you differently. Start preparing yourself for that reality now. No matter how strong of a student you are, it's going to be a draining and stressful process where you constantly believe you did not learn enough to pass. That said, the euphoria when its over and when you found out you passed are immeasurable. Will also lead to two of the drunkest nights of your life that you will never remember.
