I think it should at least be an option. The transition from high school to college isn't always an easy and smooth transition for everyone. Some students need more preparation....as far as how they can pay for college, or just mental preparation. The problem with the education system is that they expect every student to be at the same pace....they need to acknowledge the fact that students are different, and so are their personal needs.
I don't think social media is a necessity for children. Sure it's fun, but it takes away from their reality and the essential things in life. Also, there are a lot of negative influences like oversexualization, and profane/vulgar content that they should not be too exposed to quite yet.
