I can't help you with the second one, sorry. the whole writing your highschool plan in middle school is B.S. I changed my direction completely.

If there is one class that should be required for high school graduation it should be Home Economics of some sort. No matter what profession a person goes into they should have a grasp on how to take care of themselves. A typical home ec class includes brief rundowns on how to calculate a monthly budget, how to cook a basic meal (so you aren't just surviving on instant ramen), how to write a resume, how to sew a button or mend a garment , and how to manage a social group/ interaction. In my opinion, each of these should be considered the examples of why it should be required because they are necessary whether you are going to be a janitor or a doctor.
