I take Health online to free up an elective. Let me just say it's a serious commitment. If you don't understand something there is NO ONE to help you. Learning health is one thing, but I can't imagine learning Trig, Algebra, Foreign Language, Chem, or, Physics without any one's help.
This also means these girls get no extra curricular activities such as art, band, chorus, theatre, or any of the various school based clubs and service organizations not only for their personal enjoyment, but to put on college applications. They will not go to homecoming or prom unless invited, and they will not attend a formal graduation. I could absolutely understand giving these things up if you were an Olympic bound gymnast, ice skater, swimmer, or something like that. But, the bottom line here is, cheerleading is not an Olympic sport. You can't make a career out of being a cheerleader (unless you go pro, and then why bother training to dance pom) unless you want to coach or own a gym of your own. Eventually your Allstar career will end. And you will move on, most likely to college where most Allstar kids want to cheer. These girls will most definitely have the skills to make any college squad they want with all that training, some might even get scholarships. But back to their college applications. What are they going to put on them? I don't know much about this particular online school, but in Olympic bounds cases usually you come out with a GED or a standard diploma. What are they going to put on their extras? Cheerleading? I assume most colleges understand in the case of an Olympic athlete and are happy to make concessions to have some one of that prestige attend their school. But again, these are not Olympic athletes, and the admissions people will likely have very little idea what Allstar cheerleading is. I'm not saying these girls will not get into college. But it seems to me this is an awful big commitment to a gym, and an awful big educational risk all for a World Championship.
