Hello student, when it comes to the subjects of physics and mathematics, there would be very less number of direct questions or the questions from most wanted books like arihanth series without change is values.

If its chemistry, then in in organic and all you can expect direct questions since they are theoretical.

But in physics, there would definitely be chance in changing atleast 1 value since most of the questions are problems. At ,as there would be 2 to 3 questions which can be seen without change in values. Even these 2to 3 cannot be from same book

so I would suggest you to go for the concepts
