<p>For most students, they are generally better off taking more classes and also doing more extra curriculum and research stake up on awards since there is really no advantage for applying early. You can do a lot in a year. For me, being a senior is just super fun! we get all the good parking spots and you can finally be like the oldest in the school. He should at least try to get a hs diploma if he is graduating early( by taking the required courses) , even if some colleges doesn’t care.
And about the advanced classes. about 2-3% of the kids at my school run out of math classes in sophomore year, and about 20-30% are done their junior year, you don’t see all of them graduating early. If you are out of classes for a subject, take it at CC, online stuff, or explore advanced classes for other subjects. it shows you have initiative to take opportunities.</p>
