Can I get my gpa up to a 3.5 or 3.6?

I am going to be a Junior and my gpa is currently 2.8. That is because freshman year i got mostly Cs and a 2.7 gpa and this year i only got 1 C but my gpa only went up .1 . I am taking honors Algebra II and a school offered Business Dual-Enrollment course and everything else will be a regular course.If I get As for all the regular courses and Bs for Algebra and business can that raise my gpa up? Then Senior year I’ll thrive to be in all honor courses and do well in those. It is possible to raise my gpa up to a 3.5 at least? All my classes freshman and sophomore year were regular courses.
