You have to fill out the form honestly and completely. You would be better off talking to a financial manager/planner if you have a lot of cash on hand anyway - you want someone different from the accountant who does your taxes because they keep each other honest. None of us here know your financial profile (and we shouldn't), so we are not qualified to advise you.
If you live in Westborough as your profile states (as I do), you should attend the evening sessions re college prep at the high school. BUT (important) we were advised to look into MEFA (Massachusetts Educational Financing Authority) for funding (although it's late for you to do that for the child in question) and now there were reports on the local news this past week or so about irregularities and rip-offs. MEFA itself wasn't the problem, but the company they outsourced their billing/accounting to has devastated families and students with debt. I'm so glad now that we didn't go that route. You can check with the attorney general's office and a financial planner about how to get money out of that program if you have used it. You can go to the Boston TV stations' websites for the report.
You will also find that the financial aid offices at the colleges are very helpful, and your child should be open to more than one college to be able to go where the aid is most generous. These offices continue to be helpful through the 4 years of attendance, mixing together a bit of a patchwork of need-based and merit-based aid.
Aid is a mix of federal student loans, federal grants, individual college aid, college scholarships, possible work-study, and some local scholarships (Westborough High School and local civic organizations have hundreds of small ones available, but they add up). Your child should get a list from the guidance office and start looking early on at the requirements, essays needed, and so forth.
Finally, do not put the loans in YOUR name, but in your child's name even if you plan to help the child pay them off. Payment rates are based on the child's starting salary after college, rather than the parents' income. You can still give your child some of the money to pay them, but neighbors of ours really got hit with huge payments because they co-signed those loans.
