hello tejal......

for open category in jee main there is no requirement of any qualifying marks in each and particular subject that rule only applicables in advanced and not in jee main but in jee main you should score the marks according to your category on the basis of over all paper

i hope this information is helpful

all the best.

There is no criterion for Individual marks in JEE Main, what You need is that You total marks in all the three subjects should be greater than the cutoff set by JEE MAIN, cutoffs for all categories vary every year and depends a lot upon the level of question asked in the exam. From the Previous years trends anything in the range of 90-100 should be sufficient to qualify JEE Main, but remember that this year there are two attempts for JEE Main So expect some rise in Cutoff from Previous years, and it can be told after both papers get over.
