Can I submit my 90-day report early on a student visa without losing days of stay in Thailand?

I'm in a 1 year student visa. My first 90 day report is the 22nd September. Meaning that the second one should be around the 19th December.

The problem is that I want to be in my country for Xmas from the 11th to 31st December.

* I can do the report 15 days before the limit date, right?

* If I do it that early, means that Immigration will deduct me those days from my total visa? In other words: If I do it the 10th instead of the 19th, the next report will be the 7th of March, instead of the 16th, having lost 9 days of stay?

Thank you
