Hi Aspirant,
BYJU's is good for preparation.
You'll get lectures and have access to questions as well.
For better preparation,you can also go for test series of other institutes where you have national rank for a wide number of participating students.
Hope this helps. 

Hey Yash Prajapat,

Yes, it is useful but not better than live coaching class. ofcourse you’ll be having assignments on each topic. But if you go to live tuition classes you can ask the doubts to the faculty and you can track progress with the help of them!
