I got into UIUC for Mechanical Engineering in February, and I even got into the James Scholar Honors Program. I live in India, but I’m a US citizen, so I’m considered OOS. I did pretty bad in my final exams. I’m in the AP/Telangana Board of Intermediate Education (A state board). In this board, only the marks of the final exams at the end of each year count towards your final grade. In 11th grade, I scored:
French - 95/100
English - 92/100
Math 1A - 70/75
Math 2A - 70/75
Physics - 53/60
Chemistry - 47/60
That’s a 427/470 (90.85%)
The rigor of the Math, Physics, and Chemistry courses is about the same as that of an AP course. French is mostly the basics, and English is not at a high level. Those are my 11th grade marks. I got my 12th grade marks today. They are:
French - 91/100 (4 marks less)
English - 85/100 (7 marks less)
Math 2A - 47/75 (23 marks less)
Math 2B - 38/75 (32 marks less)
Physics - 43/60 (10 marks less)
Chemistry - 34/60 (13 marks less)
Physics Practical - 28/30
Chemistry Practical 28/30
That’s a 394/530 (74.34%)
Pass marks are 26 in each Math paper, 21 in Phy and Chem, and 35 in Eng and French. So I didn’t fail anything. I didn’t barely pass anything either, except Math 2B and Chem maybe (Passed by 12 marks and 13 marks, respectively).
Overall, that’s 821/1000, which is 82.1%. I know I did bad, but I honestly wasn’t expecting these marks. I was expecting around 857. The AP board is notorious for bad evaluations, but UIUC doesn’t know that, so I can forget saying that. Do I have a chance of getting rescinded? Above 75% out of 1000 is an A, that will show on my transcript, but there’s no other grades. Only the marks show on the transcripts, and an overall A, no percentages. I honestly have no excuse for my marks. I was lazy, and I didn’t study that hard this time around. I only did good in Eng, French, Phy Practical, and Chem Practical. Math went down significantly. So did Chemistry. The only engineering-related subjects I did good in were Phy and Chem Practicals, and Phy I did okay. So will I get rescinded? Sorry for the long post. P.S. I got a 9.8 GPA in 9th grade and 10th grade, when I was in CBSE, if that helps at all.
UIUC doesnt care about your school grades if you are an International!
They dont ask for school grades if you are not an US resident.
Only 10th Board marks are required
You would be fine mahn chill 
Yeah, but they only see my 10th grade board marks while applying. Now that I’m in, they look at 12 grade marks right?
For US students you have to really tank it --as in Cs and Ds-- on your all final semester grades for admissions to even think about rescinding an offer. I think the above advice to chill is appropriate in your case as well. If your GPA now falls below the James Scholar requirement that might be an issue, but you can always reapply for that designation.
@GCBMIB My Math 2B score and my Chemistry score seem like C-'s to me. My Eng, French, Phy Practical, and Chem Practical scores are pretty much A+/A’s. My Phy score is like a B-/B. My Math 2A score is like a C+/C. So, it’s almost like A+,A+,A+,A,B-,C+,C-,C-. 3 C’s can’t get you rescinded right? UIUC might consider the Math 2B score to be a D as well. I guess I can’t convert like this, but it’s a rough idea. And @JANSAT2400 They only see my 10th grade board marks while applying. Now that I’m in, they look at 12 grade marks right?
I think you are probably still fine. Rescinding admission is a big deal. Typically it is done, if senior hijinks or some other crime makes the news or is reported to the school or if someone falsified/provided misleading information on the application. A call to admissions would get you a definitive answer on your situation.
Yes, exactly what is been said above ^
@AGDC18 You have got into UIUC now. They have accepted you for a term of 4 years and you have commited back as well. They can rescind you only if you have gone against their honor code and they have found that out somehow.
