Hello Rahul Kumar Ram.

Yes, this might cause an issue when you will be going for admission in particular college, because you will be asked to submit a bunch of documents including your 12th marksheet.During the admission process, each and every details are matched before admission process begins. Since there is no more room for correction, all you can do is inform the officials of college as soon as you submit the documents that you have a marginal error in 12th percentage, THEY MAY CHOOSE TO IGNORE IT.

Good Luck.
