<p>Yes, your stepmother’s income will heavily affect the aid, though your brother going to college may alleviate some of that. That there are others in college would also impact the the numbers too. How any given college will take that all inot consideration, I don’t know. There was a post where someone asked the same thing about how stepsiblings going to school should be reported. Since I don’t know the rules, I won’t respond to this, though I would fill it out as generously to yourself as possible and let the school decide how it will handle this. It can vary among schools a lot. Good luck.</p>
