Dear Rashika,

If you have came across your college's website and it shows the classes are going to begin, that must be true but It can be of senior students or freshers, you can confirm that too from the college itself. As the colleges and universities are opening, the classes may be offline only in case you have opted for an online course, then it is definitely going to online. Also, sometimes the college doesn't personally messages you the classes details, you may get official emails, you can check that.

Moreover, as you haven't provided the college's name, I would suggest you that you can further enquire from the college itself. You can contact them through the contact details provided to you at the time of admission or you can get contact details from the college's official website too.

Hope this helped.

All the Best!!
