I don't think that tanning beds are necessary for children-- kids until 16. I realize that it is nice to have "color", but it does a couple things, in my opinion. 1) It builds our self-obsessed culture that we have to look good at all times. 2) Tanning, in moderation, can be good because of the sun's rays; however, tanning booths are not necessarily giving you the sun's positive rays.
Isn't it your choice to risk your GPA? Also, aren't you getting a FREE college class at the same time? If you are getting basically a free college education, isn't that worth risking your GPA? I think it's like having your cake and eating it too.
Who defines effort? Why does effort in a class that has been deemed "college-level" mean more than effort in an band class? So, you're argument is that if you have a lot of homework, you deserve more credit? If you have a lot of work at night, could it ever be that you waste your time in school? What if someone spends a lot of time on a painting for art class? Should they be allowed more credit than someone who can paint in a moment?
Who is to decide the hierarchy of classes? College Chem requires more work than an art class? The argument you're making smacks of elitism, and it makes it appear that people who excel at things like fine arts are as important as those who are college bound.
