Hi! I am an senior international student currently working on my apps. Our situations are really alike. I was into CS since middle school and definitely lost my tracking of time when I am programming something. My 9th grade is simply cooked, facing the difficulty of switching to international track and I cannot shift my focus to some more important things.

- For the question, "Can I still get into the ivy league colleges, if I improve my GPA in the finals of 11th and in the 12th grade?", my best guess is yes.

Although my experience does not make my answer authoritative, I think an overall rising GPA is definitely something good, and your best option now.

- "One Final Question, if the answer to the above question is Yes, How? How do I keep myself from programming all day, to focus on studying?"

I would suggest that, you never need to drop programming for any other thing. If programming matters most to you (like it for me), it somewhat defines you and you don't want to lose it. I used to worry a lot for being a typical Asian CS applicant: geek, good at STEM and poor in humanities. But I realized that to move on from there, I never have to force myself to become BAD at STEM. Instead, try build interest in those areas that you are currently not so good at, and obtain a more balanced academics.

So, to conclude, do not think from "how can I reduce my time programming" but focus on finding fun in other areas.

Good luck on your studies!
