Can I Self Study for the US history regents?

I’m currently a freshman looking to self study for the US history NYS regents somewhere through the 10th grade school year. I have a good grasp on history and am taking AP World History from 9th grade to 10th grade. Will it be possible for me to pass US History through self study. I heard it was quite easy, obviously not simple but the easier regents. I will be taking AP Chem, Trig and English lit so would the workload to be hard to sufficiently self study. The reason I ask this is that with an 85 (This is required, by passing the regents I mean above 85) on the regents I can skip the mandatory course in 11th grade and take AP gov macro or micro or someth like that, or at least have open periods. I would also be open to studying over the summer

Are you sure that the requirement is an 85 on the Regents, with no mention of actually taking the course?
