sir if i got 476 mark in neet then what we will be fees for obc quota

You haven't mentioned your Category. Nevertheless, in 2019, under State Quota for Government seats the cut offs for various Categories have been as follows:

General Category: 410

SC: 325

ST: 165

OBC: 373

Now this is 2019 data and cut offs change every year. Cut offs change every year depending on various factors such as no.of Candidates appearing for the exam, no.of Candidates qualified, top NEET score and difficulty of the exam. Now for 2020, if you secure 450 and more, you are likely to secure a seat in Government Quota. Under this, the fee for the entire duration of the course might be anywhere from 15,00,000 to 20,00,000 Lakh Rupees for the entire duration of the course. This is adhoc fees and might be changed according to the Government of Gujarat Regulations.
