Yes, it is worth it not just because of JEE/NEET preparation but for the various reason-

1)Meeting great people-If you are coming to Kota, you are going to meet a lot of great personalities example HOD's and directors who are running the whole institution. If you are in the top batch, you will get a chance to interact with them daily. Sometimes they motivate us with their own memorable life stories.

2)Competition- Most of the NTSE, Olympiads schools are here, so you get a chance to compete with them every month, and many institutions have batches like the system so you can feel the competition every day.

3)own Decision making- you get a lot of freedom to do whatever you want in Kota, but you have to decide the best for you.

4)Friends- You have never seen a class strength around 100 and never interacted with many people of different backgrounds if you are in Kota. Your soft skills are going to improve.

5) Discipline- Study gets harder and harder each day, so you have to work hard daily and manage time properly, which you will learn if you are preparing in Kota.

6) you are going to face pressure and depression. I consider it as an advantage because, at some point in your life, you are going to face it, so why not early.

Still, there are many pros and cons, and I guarantee you will definitely going to change but good and bad is always in your hands.
