<p>Knowing how a teacher works is a must. For each teacher, you’ll have to push different buttons (not literally). This year, doing the homework in physics barely kept my grade from falling to a B+ (I scraped by with an A- …hardest A- earned ever), but for math, he never checked, so I slacked off towards the end of the year.</p>
<p>Get used to the tests in each class, too. I always reread chapters for APUSH because all the tests consisted of MC questions based on the reading.</p>
<p>Have a study plan. If you have a big assignment assigned ahead of time, spread it out so that you’re not stuck working on it 'til 2 AM the day it’s due. If you have sports and ECs, I know you’ll have even less time, but if you get assignments ahead of time, you can get ahead by waking up earlier on weekends or skimping on homework that you know won’t be checked.</p>
<p>I’m not one of those people who doesn’t put in any effort but can still get A’s, so I sacrifice a lot during the school year to keep my grades up.</p>
<p>Eat well and sleep well (I know the latter’s hard). Keep your body healthy so that it won’t crash too often. I can’t help you with the being sick issue. I’m lucky in that I only get sick a few times a year (I get really sick, though), and by sheer luck, those times are usually around vacations.</p>
