can anyone pls tell is fiit jee best for jee ??

Hello aspirant

FIITJEE has a many coaching centres across India so we can't estimate which is good among these many centres.
I'll give a clear glance about advantages and disadvantages below

Advantages:

They have a very good resources where you can find many problems and theory of a topic you choose

They have their own strategy in making the question paper apart from coaching they give you many papers which helps you to practice your skills

Faculty knows well about the concepts and content to teach.

Disadvantages:

As they have many problems on every topic it is difficult to filter the good problems.

As there will be many students you can't have a proper attention compared to smaller classrooms.

It all depends on the way you are sincere, dedicated and passionate towards your exam. Every coaching centre has its own advantages and disadvantages.
At the end of the day you will be responsible for your marks , rank whatever it might be.
Just with a coaching centre you can't crack the exam its you who should involve yourself and learn the concepts.

Hope this helps you

Good luck!!
