Can you share your score background please?I thought it went well, questions were very straightforward with probability (combinatorics mostly) some programming and some calculus. No need to really review extensively although you may want to brush up if you've haven't used these concepts recently. Good luck to everyone!
I didn’t have any problems completing the essay part. I think you should write an email to admission team and describe this issue in details with screenshots attached. They will definitely help you resolve this technical issue.
Just email them or call them. I went into similar issues in application for another program and the committee fixed it for me immediately after the phone call.
