Withholding an APCSA 3 for international CS Major

I’m an international student applying for CS Major for T20s, ED Columbia. I got a 3 in 2020 APCSA, so I was really frustrated about it. So the question is, considering I’m an international CS major applying for T20s, should I withhold the 3 for CSA? I currently enrolled to 2021 APCSA and are definitely going to mention it on my Commonapp. Also I got an A in my school’s APCSA class from one of the most rigorous teachers in our school, so I’m confident that my scores will rise next year.
