Admission to University of Southern California

Answered

I am an Indian student (12th just started, batch 2021) currently preparing for JEE, an entrance examination for an Indian engineering college. I have recently started to acquaint myself with admission to U.S. colleges, especially USC. I plan for a CS major. I am not quite able to decipher the college website about submitting the college application. Here are my queries regarding it:

1. When submitting through common app, do we have to submit a common app essay as well? I know there are 2 supplemental USC essays (2 more for CS) with 12 short answers. Anything extra?

2. I would have my education completed upto 12th with English as the medium of instruction. I will also take the SAT, which will further prove my proficiency.

Do I need any additional English tests?

3. In our country, there is no 'GPA' system. We get a solid percentage in almost every exam. How are these GPAs calculated, which will be considered in the admission process?

4. Any additional info- which I (an international student) should be aware of....? :)

Thanks!!
