<p>Colleges usually don’t care about your grades unless you’ve met a basic academic/scholastic standard as evidenced by test scores and class rank and/or GPA. You can have the toughest courseload there is, but if your grades are mediocre, you’ve really torpedoed yourself.</p>
<p>I worked not that long ago at an elite prep school. A really high percentage of the students made it into Ivies, and most of them hadn’t taken the absolutely most rigorous courseload.</p>
<p>I will reiterate that very few admissions officers would consider Physics C, AP Stats, and AP (insert humanities) as a light or non-rigorous courseload. I challenge you to go to Harvard or Stanford or Princeton or wherever and try to find candidates who have Physics C, Differential Calculus, and an AP language. Most students will not have taken a differential equations and Physics C level course by time they graduate from an Ivy League school, much less by time they graduate from high school! If the OP can take these courses and do well in them, then great. But if he’s going to struggle – <em>as he said he would</em> – then it can do more harm than good.</p>
<p>If the OP has a 3.5 GPA now and it goes down or stays the same because of a bunch of B’s, then he’s bordering on not even making the first cut at top tier schools unless he has near perfect test scores or he’s from a school that receives special treatment in the Blue Book (and if he was from such a school, he’d probably be asking his word-class guidance counselor this question). </p>
<p>Here is the reality of “high stakes” admissions:</p>
<p>He can struggle with the difficult courses (his prediction, not mine) and have a mediocre GPA.</p>
<p>He can excel at tough AP courses and still have a very strong course load (just not the absolutely maximum super rigorous courseload that 1% of candidates have) and have a decent GPA but run the risk of an admissions officer noticing that he didn’t take the absolutely maximum super rigorous courseload.</p>
<p>My experience has shown that a mediocre GPA/class rank is more debilitating to one’s admission effort than taking a very rigorous courseload, but one which isn’t the absolutely maximum super rigorous courseload. AP Calculus and Physics is just fine for most schools, and two AP maths and two AP physics is really serious stuff (which is what I think the OP might have with BC Calc, AP Stats, AP Physics, and Physics C).</p>
