It seems counter intuitive, but for many students, the PSAT (practice SAT) is more important than the SAT. It certainly was for me. The SAT scored required to get into my school of choice was pretty trivial at that time, so I wasn't concerned with it at all. The PSAT was the starting point for deciding who gets money. I paid for my first car with my PSAT. I'm not sure if the rules have changed since then (I took it decades ago), but it does pay to know the rules of the scholarship game before you start high school.
Another note, one should NOT put money away for a child's education until your retirement funds are on track to provide for you in the future. The time horizon for school funding is shorter but your need in retirement is so much greater so it takes longer to save.
I wholeheartedly agree with that. You can finance college with borrowing if you have to. You cannot finance retirement. Before you think about saving for college (a nice to have), you need to make sure that you have your financial basics covered.
1) Make sure that you are on track with your retirement savings. It can be a bother to calculate it, but it is much better to waste a few hours every year or two than it is to be forced to choose between working well into old age or taking a huge reduction in your standard of living.
2) Make sure that you have a reasonable emergency cushion. If current events don't make it abundantly clear, your should have 6 months of expenses in a reasonably stable and liquid place.
3) Make sure that you have adequate insurance - life, disability, home, health, etc.
4) Pay down any high interest debts and avoid taking on any more.
Only when these things are done should you start saving for college. Of course, those things should be done regardless of whether you intend to ever pay for anyone's college.
