Hello Aspirant,

See generally mock tests and sample papers are little bit hard as compare to usual exam paper, this is because the student should prepare himself/herself for that type of mock tests and he/she will be prepared for that mock tests than he can easily crack the usual exam.

If you are facing the above problem than there might be the two reasons either you have not that much preparation which is needed for clearing mock tests or the questions you have solved in JEE-Main 2020 paper are used to for you means that you have limited knowledge of concepts.

So there is no need to worry, still you have more than 1 month left, what you have to do is just collect as many mock test series and sample papers as you can and start solving them because as much you solve it you will have clarity of topics in your mind.
