Schools need to teach life skills!

We need to teach teenagers life skills such as paying the bills, how to set up a bank account. These are things we will be need in our later life so why don't we learn about it in school to get ahead . Yes our grade are important but so are our life skills I think schools need to have a lesson or a day for year 11, 12 and 13 students to teach how we do things like paying the bills etc
