Chances I can get into U of Michigan?

I am going into my Junior year. I'd rather not go into depth on my freshman year... Let's just say I didn't take **** seriously and I got a 76 average for the year. I am very smart though, I'm just known to be lazy when it comes to studying, etc... Well I stepped up my game Sopre year and the only cl I struggled in was Trigonometry (I was placed in Algebra 1 in 8th grade, never should have been, I'm terrible at math and now have to deal with being a year ahead when I shouldn't be). I got around an 85-87 average for the year last year. I plan on taking an SAT prep cl this August and take the PSAT. If I can keep my pace and get around an 85 my Junior year, get a good SAT score, and then have a very good 1st semester Senior year, do I have a chance of getting into Michigan? I'm really pissed at myself for slacking my freshman year. What are my chances?
