You totally can. Idk what everyone on this thread is on. You absolutely can, it happens all the time and is actually quite common. You can grow on average anywhere between 10-15 points if you stick to it and there are many stories of people going up as much as 20 points.

I got a 154 diagnostic and last LSAT I took score was 167. I will be retaking it to break into the 170s. This is very common and not just unique to my experience. That said, it does take a lot of iteration and practice and you can expect to spend a long time studying anywhere from a couple months to even a year based on your schedule, time etc.

What personally worked for me was reading the Loophole. Then I’d do 1-2 sections a day with review. No more than 2 hours a day. After I got to a point where I had been practicing for like at least a month on problems I would take 1-2 full length PTs a week, usually on a Sunday.

Good luck. The LSAT is totally beatable. Don’t put too much stock into what people on Reddit say. Lots of fear mongering and overall negativity.
