Rishu, we want to answer this question by quoting from the NTA Information Brochure itself. You can check the same at Page no# 13 pf https://jeemain.nta.nic.in/WebInfo/Handler/FileHandler.ashx?i=File&ii=256&iii=Y . It says" Passed qualifying examination with Physics and Mathematics as compulsory subjects along with one of the Chemistry/Biotechnology/Biology/ Technical Vocational subject". It says Mathematics should be a compulsory subject. If you take up super medical stream in PSEB, you will have Mathematics as an extra subject. And so you are still eligible for JEE Mains and JEE Advanced provided you study Mathematics both in your 11th and 12th. It doesn't say Core subjects but only says as compulsory subjects. And the reason why PSEB has Super Medical Stream is to let Candidates also explore options of other streams.

Hello,

To be eligible to get admission in IITs you must have studied Mathematics and Physics as compulsory subjects along with Chemistry/Biotechnology/Biology/Technical vocational Subject. You must have score 75% aggregate if you belong to general category and 65% aggregate if you belong to SC/ST category.
