Dear Aspirant

I like you confidence in getting a 300 ST rank in JEE Advanced.in general getting a 300 rank in general category is really very difficult.There is a huge computation in the present times. And getting 300 ST rank is also very hard.the rank never depend on marks for exams like JEE Advanced.so it unpredictable to say.And jEE advanced marks scheme are never announced. but on a average if you able to score65 percent of marks you can get the rank which u are aspiring for.
