I'm 16 and I'm going to be a junior this September. I haven't failed any classes since Middle school. I don't get perfect grades, I mostly get C's and B's and maybe an A or two. My sister and my mom keep telling me that if you get mostly C's you will be forced to work at Mcdonalds. Is this true? When I turn 18 I'm going to a Trade school to learn computer stuff. But the question is, do you need to have straight A's to get a really good paying job? Can someone with my grades get a good paying job? I occasionally get a D, but it goes back up.
