Kya hum jee online 2018 and jee offline 2018 dono exam de skte hai??
I advise u to choose offline mode bcz previous year online paper was much tougher than offline ones.

No bro,
You cannot you can only give one exam at a time . There is no need to give both exams because they are same but the modes are different.
Hope it helps
Good Luck :)
