Exam Centre – Where is the one in the Isle of Wight?

Hello,

I wondered if someone could tell me where the exam centre is in the Isle of Wight?

I live in Portsmouth and I am stuck on if next time I should go to the Isle of Wight or Southampton. The exam centre in Southampton was not very easy to find after I got off the train and its the worst feeling ever to think “im lost!” half an hour before an exam.
