Dear student,

All the online resources, that you have mentioned in the question are good. You can choose anyone from these. But in my viewpoint, you should go for unacademy. It is one of the India's leading online education platform. You will find many great teachers here. Also, you can join Akash as well. It is also good.

Rather than these preferences, you can solve previous year NEET question papers for better performance. And also, solve as much mock tests as you can. If you are willing to choose some online platform, then alongwith it follow some good books like HC Verma, OP Tondon, Trueman's etc.

Hope this helps.
