Some students can take the hardest available classes and still do well, have fun, and sleep regularly. But everyone has different abilities. Part of being successful in high school means pushing towards, but not past, your own academic limits.
You should enjoy your activities. You should get enough sleep. You should see your friends, have fun and occasionally do things that have nothing to do with college admissions or improving yourself.
There is nothing wrong with a course schedule that demands hard work. Some stress and the occasional late night are OK, too. But no college in the world would want you to make yourself unhappy or unhealthy because of your classes. Even the highest achievers still need to be happy and well-adjusted teenagers.
If you’re hoping to go to one of those schools that rejects most of the people who apply, you’re going to need to take the most demanding courses offered at your school and you’ll need to get A’s in just about all of them. But most of the over 2000 colleges don’t demand that kind of perfection from their applicants.
Work hard and take classes that challenge your academic limits. But balance that rigor with reality so you can be a happy and well-rested teenager, too.
