Feeling a little discouraged, need advice

I just received my score for the September 2019 LSAT (first time I took the exam), and got a 155. I REALLY want to get to 160, and am planning it to take it in June/July 2020 (whenever the exam takes place). I am a little disappointed with my score, as I studied quite hard and was scoring at about 160 in my PT.

I am currently a Junior in university so I have some time left still. What is the best way to increase my score at least five points, if anyone has any advice that might befit me I would greatly appreciate it.

Thanks!
