Indian marksheets.

So I have gotten my SAT scores and I’m looking to apply in the US. But I have a few doubts.

I have my class 9th and 10th CCE marksheets. And I have also done my 11th in the same school. I am now in class 12 and I’m about to finish it.

There is a deadline for all the colleges around January and February. But my class 12 boards wouldn’t even have commenced by then. As a result I will not get the results till April. Then how will I submit the 12th marks?
Is an estimate from the school enough?
This is because the application to colleges require at least 8 semesters of the required subject and the deadline is before I can get the 8th semester. The response from the college will also be received before the results come out.

I have done all 4 years in the same school and board i.e. CBSE.

I hope someone can clarify my doubts. Thank you.

Send the most recent scores (Usually quarterly or half-yearly) along with predictive scores

This is a normal issue. Early deadlines in the U.S are usually in November, and Regular Decision for elite schools are at the beginning of January. Some less selective schools have later deadlines. Regardless, you can send whatever predicted grades you have, or grades for the end of your grade 11, when you apply. You then send your updated marks once you receive them. Some universities, such as the University of California and University of Washington, do not even consider your grade twelve marks. You will be evaluated by whatever your grades were as of the end of grade 11.
