Hello aspirant,

Just concentrate on one thing at a time and don't think about the other while studying for one exam, regarding your concern for the leniency in the exam we can't tell you that as there is no official notice, In board exams you should focus on NCERT and be thorough with the concepts and have a good practice for each important questions.

Due to Covid-19 there has been a delay in exams so there will be a rush in checking the papers so there is a thin scope of having some relaxation to the students that is all what I can say so just prepare well and do well in your exams.

all the best!
