Can I Get To A GPA Of 3.0 By The End Senior Year?

No, you can't. Sorry. Even if you got nothing but A's this semester and all next year, your highest possible GPA would be (1.9 * 5 + 4.0 * 3) / 8 = 2.69, uming you take about the same number of cles every semester. And of course, that's by the end of senior year, and it's too late to apply to colleges at that point.
