Hey!

It totally depends upon you. If you feel like self study is sufficient for you then no need of taking coaching. Coaching classes are not a mandatory factor for clearing of any entrance exams. There are many students who excel in competitive exams like jee mains and advanced solely on self study. If you feel like your base is week and you are struggling with concepts and need guidance then yea definitely try for coaching or youtube learning. But if you have a good grasp of concepts and just need polishing (as visible in your score) I would suggest self study. But then final decision is yours.

The basic thing about coaching like Allen FITTJEE is that they constantly take examinations and that help polish your concepts and numericals. But you can get such exams online for free like NTA abhyas and many more.

You can even solve the last ten years iit question papers available easily on the internet. The thing is everything is available for free on the internet if you search for it.

And if you still feel that you need coaching then definitely go for it. It totally depends on personal needs.

With the right motivation and study materials you can excel in the exam without any coaching

Best of luck!
