See there can be typo's which happens all the time. Although you must have been very sincere while form fill up but as you have done mistake lets forget that.

Now there won't be any problem while giving examination. There are no such issues related to school details during the exam hall attendance. So you can go for giving the examination. This might create some issues during document verification although getting your application cancelled for such a case is very less. I would say you can ask the helpdesk via email or call about your problem and if there are any ways they will give you the procedure. Don't worry about this, just focus on your examination.
