Chances into UIUC, USC, UCLA, UCB, UOM (ann arbour) or Cornell?

Okay so this is a bit long but please read!

Currently studying in an IB school as an international student from India, I have just passed my 11th grade and plan to pursue mechanical/electrical engineering abroad.
I scored a 92.2% in grade 10 and I rank in the top 6% of Grade 11 in my school, but my marks have not been great as it is a very rigorous school and also due to the following reasons:

       ***11th GRADE***

Semester 1:
Coming from a state board (a totally different curriculum) I entered into grade 11 with loads and loads of extra-curriculars (which I undertook in the vacations) based on a very strong passion that I pursue for the betterment of society. Due to this sudden change in school-curriculums and time spent on extra-curriculars my grades were’nt top-notch in the beginning.

Physics HL - 4
Math HL - 5
Business Management HL - 6

Chemistry SL - 5
English SL - 6
French SL - 6
TOTAL = 32 out of 42. (roughly 3.4 unweighted GPA)

Semester 2:
I started concentrating on studies and managed my time efficiently because I knew that I was much better than this. I aimed for over 39 on 42 and my internal test grades were great (almost 6s and 7s in all tests) but I again took another big hit as unfortunately, just a week prior to my final year exams, my best friend passed away due to a high fall, which came as a huge shock to me. I tried very hard to maintain focus through all the sadness, deep messages from friends, multiple invitations from his house for final family rituals,
and in the end I did improve but not with what I expected.

Physics HL - 7
Math HL - 6
Business Management - 5

Chemistry SL - 6
English SL - 7
French SL - 5
TOTAL = 36 out of 42 (roughly 3.6 unweighted GPA)

  ***12th GRADE***

Semester 1
Started focusing ALOT on academics after a vacation full of hardwork both in extra-currics and studies.

Physics HL - 7
Math HL - 7
Business Management HL - 6

Chemistry SL - 7
English SL - 7
French SL - 6
TOTAL = 40 out of 42. (roughly 3.9 unweighted GPA)

PREDICTED GRADES
My teachers have to predict our grades that we may attain in the final IB exams, and currently my predicted score is a 41/42.
(one mark still down in Business Management!)

OTHER EXTERNAL EXAMS
ACT = 35

SAT II PHYSICS - 770
SAT II MATH - 800

QUESTION:
What are my admission chances into UIUC, UCLA, USC, UCB, Cornell, UOM ann arbour
or into any good college infact!
AND will colleges like this sort of an upward trend? Do they prefer consistency or improvement?
Looking at my marks, will they think, even for once, that I kinda slacked off in the beginning? (even tho I did’nt!)
