1)Homeschooling education varies. Depending on how qualified your tutors/parents are there’s no guarantee they’re education will be enough to adequately prepare you for a career in the future.

Yes, some public schools are horrible-but they at least provide you with sufficient standardized tests to ensure you at least get a “decent” education.

2)Probably the most obvious one, if not it should be. You’ll find when you get older that book smarts will only get you so far in the work place. Social skills will take you a long way, in fact it’s your ability to communicate which will probably get your foot in the door. Dealing with/Getting to know your classmates will help you hone those skills.

Summary:

Go back to school, there’s more to life than hitting the books and staying indoors.
