When will NSEP , NSEC and PRMO registrations begin . ALSO HOW TO PREPARE FOR THOSE EXAMS ?
Hello Jayant!
PRMO registrations have already begun. As for NSEP and NSEC, you can receive updates from www.iapt.org. The PRMO syllabus consists of four topics: Algebra, Number Theory, Combinatorics and Geometry. The well recognised book for Mathematics Olympiad preparation is 'The Excursion in Mathematics' which I think you may find useful. Just follow the JEE syllabus to prepare for NSEC and NSEP.
All the best!!
