Hello Aspirant,

No not at all your marks will not be deducted if you take a drop it will remains same. If we talk about eligibility criteria so that might change for next year which is little difficult but still no any major change would be made which will stop students from giving JEE-Main, but yes there will be the change class 12th marks eligibility criteria which has been removed for this year in the wake of COVID-19 Pandemic but from next year it will be considered so if you have secured 75% marks or more in class 12th then only think to take a drop otherwise go for any other option.

I hope this information helps you.

Good Luck!!
