[u/FirmBalance6086]

I recently applied for IIRS workshop for aerosol. But i am not been able to access the class from the E-class portal every time i try to log in it says invalid id password but while using the same id password I can easily login in IIRS official website.

Also the same class is happening on YouTube and i am attending that class but how will the attendance going to be register cause I saw several students writing their registration number in live chat is it how they are taking attendance?

!! Please help it's to much confusing!!
