Hi Apeksha 

offline examination entitles you to a lot of advantages over the offline mode of examination. in case of offline exam, one has to fulfill the OMR sheet which is very much susceptible for getting mistook as if someone fills the wrong answer one cannot change the answer which can be resurrected in Online exam of jee main.

in case of online examination questions' answer can be changed and if wrong the question can be reserved for review.

less time is wasted in marking the answer.

well, there are cons

candidates from the rural areas do face problem regarding the confidence

sometimes candidates do note down the wrong figures which is very versatile.

all the best !!!!
