The Ontario curriculum is designed so that there are ways to make up for course choices that limit you. If your messing up was failing courses, then take them again. If it was choosing the wrong courses, then go talk to your guidance teachers about how to get back on track.
What kind of things do you think you would like to do? If you were going to study something else, what sounds interesting to study? Have you had part-time jobs that you could see yourself doing more of?
Does your school have opportunities for co-op (supervised work experience that you get credit for)?
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
