Will senior year score be consider?

<p>I’m an international student who study in local school instead of international school. I got a 3.95/4.0 GPA in the past three years. I’m now preparing for the SAT by myself because all my classmates are preparing for the upcoming national exam in Taiwan. I’m now put all my attention on the SAT, so I don’t have time to do my school works. I’m afraid I’ll get a lot of B or C. Will I get rejected by the college if my score goes down a lot?(cuz I can only send my senior score to the college after the deadline) I’m very worry about it! Please give me some advice!!! Thanks!</p>
