Advice about getting into college?

You have already done what you can to impress Northeastern. I'm sorry about the side job; you should have focused your efforts more. Apply to Northeastern and safety schools. You may get in. If not, after doing well at another school, you may re-apply to Northeastern. Apply for second semester. Northeastern will have some beds empty after the drop outs from the first semester. They will see that you have done well in your first school. They will be inclined to admit you.
