Congratulations! You'll need to wait until your GCSE results come through, then forward them onto the uni. One the uni confirms these, they will be able to update Track.
What do they mean by go through clearing? Call the university? Definitely don’t go through clearing properly as that will mean you’ll lose your conditional place. After results day for your gcse next week, if you get a 4 in your maths ring them and they’ll be able to confirm your place then.
