Hi there! I am applying to Mines and I absolutely love the school. I took almost all honors in HS and have taken 1 AP (CSA, got a 5) and am taking 3 more this year (also TAing AP CSA). My GPA is around a 3.3 UW but I got an 800 on the math and 700 on the r/w for the SAT. My GPA could definitely be higher but my freshman year was not the best (no cs but almost all bs). My junior year in comparison I had around a 3.7 UW gpa (for that year alone, almost all As or A-s). I do several sports, I am a captain for one, as well as my school’s student government. I am interested in CS and I really love this school. If I apply early, do I have a chance with my scores and continued improvement over HS?
According to Mines’ Common Data Set 10% of their admitted students have between a 3.25 and 3.50 GPA, so I think you definitely have a chance. Especially because your grades are improving.
What is the highest math you will have taken by the end of HS?
Thanks for the reply 
I’m taking AP Calc AB this year.
