But please, please please-- your retirement savings need to be in an actual retirement account- IRA,401K, etc. You cannot wave a magic wand over your brokerage account when it comes time to fill out the financial aid forms and designate which assets are your retirement assets and should be excluded.
And take EVERY nickel of free money from your employer, AKA the match. Tens of thousands of people leave that money on the table every year.
