Will I be rescinded?

I got into the pharmacy school EA when I had As/Bs in all my classes. I slacked off the rest of the year and ended up with 3 Cs (in AP Chem, AP AB Calc, Physics H). Do I have a high chance of being rescinded? My counselor advised against calling them and drawing attention to it so I’m not sure what to do.

Well from what I’ve seen, many of my fellow classmates had seen a drop in their grades after acceptance. They slacked off as well and got C’s. From heat I remember, none of them were rescinded. Most people are rescinded because of D’s or F’s.
