greetings,

yes, students who have dropped a year or more can easily apply for GGSIPU entrance exam.

there is no bar in the admission process for such candidates.

however, a few colleges may ask for a gap certificate that is just a normal undertaking but that situtation is extremely rare.

refer to the following link for more info:

hope this helps.

good luck
