<p>Hello. I took AP Bio last year but I'm not that satisfied with either my AP Score or the SAT II score I got (3 and 690, respectively), so I am wondering if I should retake the SAT II for bio? Granted, I'm taking AP Chem right now and probably don't remember too much Bio, so would it be worth it? I want to major in Computer Science though.</p>
<p>i suggest u rather go for some other subject tests because bio isnt ur subject anymore!
(also, i havent heard many people retaking SAT 2 bio AGAIN)
btw, if ur gut says u can achieve above 750+ this time with proper preparation, then go for it!! 
and since u already know now what it takes to get a 750+ and where u lack in, then definitely for it :)</p>
