Dear Applicant,

I can tell you one thing, no matter which institution you go or which platform you use to study. First and former if you're able to understand them and absorb what is being thought than only it is worthy to be on such places or just leave don't waste time.

Byjus is 1 of the few platform you could study and not all credited course are perfect, each student requires teaching on different levels some platforms cannot entertain each student personally or change their level of teaching. Thus I feel it is best not to go on such platforms. At the end if they can't help you understand what you require it's totally useless. So don't waste money be smart.
