Hi there ! This is my first post. So I am an international student who has been accepted into mathematics department at UCLA. In my application, for the last semester at my insti, I gave my grade point average as 9.5/10. I was taking two courses and was hoping that I would get a 10 and a 9, making the average 9.5. But unfortunately the grades in both the courses slipped up to a 9 and a 8 , making the average 8.5/10. I haven't informed them of this, and I was hoping that it wouldn't matter. I am going to get my visa next week, and I am really paranoid that my admission may get rescinded. What do you guys think ? Please be gentle
