GPA in Computer Science

<p>I was wondering, is it hard to keep a 3.0 GPA while majoring in Computer Science. I plan on going to Queens College. Currently I have a 84 GPA. I am in High School, senior year. On the SAT, I received a 630 for Math, and 460 on Critical Reading. For a total score of 1090/1600. For the ACT, I received a 27 for Math, 26 for Reading, 24 for Science, 20 for English and 19 for Writing, and a composite score of 24. So judging from this, can anyone tell me my chances of keeping my gpa above a 3.0?</p>
