Hey Jitendra Ganesh Kommineni,

FIITJEE is best for MPC rather than Narayana junior College. FIITJEE has best faculty to teach for both IIT JEE and Mains. Where as Narayana is not that good. They mostly torture students by keeping extra classes every day till night 11 PM for exams. They make students to by heart rather than making them to understand the concepts, where as FITJEE Is not like that. It is a well reputed Institution For Engineering. There were many cases filed on naryana colleges for torturing the students. For more details about FIITJEE you can check here:

All the best!
