I have qualified my 12th from pcb background but I need to enter in btech cse for that I have two option 1 is bridge course of maths which is provided by the university where I am enrolling but it is ugc approved not aicte and 2 option is NWAC board Northwest accreditation commission where I get marksheet for whole subject which one is better and safer which would not create problem in future for higher education and job perspective or should I do anything other in pcb background course would be safe in all perspective
You can do ugc bridge course in mathematics to pursue a B.Tech,but it is limited to certain university and bridge course from NWAC board, though valid with an AIU equivalence certificate is less acceptable in India and might create problem in government roles.
so the first option is safer with some drawbacks.
Additionally,for a math bridge course recognized by IITs and other B.Tech colleges, you should use the NPTEL platform on SWAYAM .
Good luck!!
