Whenever I apply a filter like easy, moderate, hard and then chapter. It gives specific topic wise question and in it, it has 5 set. Now when I do 1 set and go back it erases all the filters and I have to do all the steps again for every 10 questions. It is quite frustrating. It takes too much time and disrupts the flow.

Does anybody know any solution?

Do u guys get tired when u start studying. I donot mean mentally ki padai nahi karne ka man kar raha hai. I mean my eyes start to hurt and it feels ki bas ho gaya padha hi nahi jayega. I feel really tired and after some hours I am okay. I do physical activity also. What could be reasons for sleepiness.
