My expected mark in JEE advanced 2020 is 47 what will be my rank I belongs to SC .
For scoring 47 marks in JEE advanced, to get qualified in JEE advanced you need to qualify in every subject whose total must cross the minimum cutoff marks. But for your marks, it is tough to qualify as your obtained marks are near to the minimum cutoff marks, it is purely dependent on your luck. Also, we can't predict the cutoff marks. Hence it is purely dependent on the minimum cutoff marks. You can check institutions and branches for your rank and category on our JEE Advanced College Predictor 2020 tool.
Hope this answer helps you.
All the best!!!
