Took Calc 1 during the summer with Orlova-Shokry. It was definitely more fast-paced than a regular math class but the material itself wasn't too hard if you put a decent amount of time into it. Right after class, I would do practice problems of the material covered. So if we had just gone over "derivatives" I would look up "calc 1 derivatives practice problems" and do what I could until I felt confident. Given that you've made A's in your previous classes, I think you should do well if your other classes don't hold you back too much.
