You should definitely be sleeping more! I feel like students are adopting this dangerous western culture of workaholism. You should seek to study efficiently by maximizing intensity within a given time. This means that you can study less for the SAT and get results. Not only does a lack of sleep deprive energy, but it’s vital for creativity and memory. If you aren’t truly engraving your learned knowledge into your brain, then the SAT becomes even more frustrating to study for as you tread through long nights and countless practice tests.
