<p>Try earplugs? And then wear an hood so that teachers won’t notice it. 
Maybe it’ll look weird but it won’t be too bad (I used to wear an hood ALL THE TIME and no one seemed to hate me just for that).</p>
<p>And then maybe you could try studying something of lesser difficulty. Definitely not challenge problems from say ur calc textbook but SAT vocab would be easier. Or another suggestion: write in a diary or do some creative writing.</p>
<p>One thing I like to do during class is write something during class so it looks like I’m taking notes when i’m really not.</p>
<p>If your teachers do mind, then if they see a calculus textbok on top of your desk, it’s an obvious giveaway. But you can try printing out some text material of something you want to learn and then it’s much harder for the teacher to notice.</p>
<p>BTW: (something Eric Cornell tried)</p>

<p>Indeed in elementary school I often kept my desktop slightly open and affected an alert-looking pose that still allowed me to peek into the desk where I kept open my latest book, as interesting as it was irrelevant to the academic subject at hand. Every so often my hand slipped surreptitiously into the desk to turn the page. In the intervening three decades I have spent plenty of time lecturing in front of a classroom of my own, and in retrospect I realize I was seldom fooling anyone. Most of my teachers probably found I made less trouble if they let me read.</p>
