Hello student ,

To be honest nothing is impossible if you have will to do , you can crack every exam. All you have to go through all the  NCERT concepts deeply . Even the diagrams , flowchart , labelling , all are very important .

Talking about its question paper so it consists of 90 questions 1 marks for each questions and -1/4 for incoorect questions , 30 questions physics 30 questions biology , 30 questions chemistry .

Total time 90 minutes .

So try to answer questions reading it twice and be positive everything is possible .

Hope , you find it helpful !
