Hello there,
If you will check the official website of SRM institute, you will get to know that the admissions for SRM engineering 2020-21 are still open with only few seats left available! There is also a notice displayed there which states: that Btech class commencement date will be announced shortly, that means it hasn't been started yet. so i recommend you to keep on checking the official website of srm to get regular updates about the same.

hope it helps!
