Hello,

 National Testing Agency (NTA) is set to release the result of JEE Main April 2019 attempt on April 30 for Paper 1 while Paper 2 result will be declared on May 15. Since the exam is conducted in various shifts, the raw marks will be converted into percentile scores using the normalization process released by NTA. The to JEE(Main) 2018 qualifying cutoff marks for SC candidates was :73 (max marks) and 23 (min marks), so this year also we can expect something of the similar order. For more information about previous years cutoffs based on categories and other information, you can check out the link below by Careers 360. Good Luck!
