I have given chapterwise tests( 60 minutes test of every chapter of JEE main level) and have taken an average of those marks. Will those marks be similar to the JEE main marks that I will get in the actual paper?

Hello Aspirant, The test you are giving is good to revise the syllabus but is quite difference from the pattern of JEE Mains, In JEE Main you have to whole syllabus in 3 hr, so you should have the ability to sit for 3hr and should have a depth of whole syllabus but the test you are giving is chapter wise you might have given the test of the chapter you feel easy and lefted the chapter which you feel tough, but in JEE Main the question from the whole syllabus, so, it can't exactly matches with JEE Main.
Chapter wise Test is good but for analysing your depth in JEE Main you should give full syllabus test, which will be closer to your JEE.
