Again, you can actually still register later, but why pay $50 extra?
It will take about half an hour to complete the registration. The SAT photo requirements are similar to those for the ACT.

October 1 - FAFSA opens for application
This isn't a deadline, but you should pretend it is. Filing early means that your scholar may get access to more aid, since some colleges award aid on a first-come first-serve basis. They'll also receive their Student Aid Report earlier, so you'll have a clear sense of where they stand.
(The one caveat here is that if you know your 2020 income will be substantially less than it was in 2019, you might need to contact the schools' financial aid offices to have your true current income considered.)
Here's a poem to inspire you:
Don't wait till June of 2021.
Just grit your teeth and get the FAFSA done!
Of course, there's a lot more to it! The SAT and ACT are offered throughout the year. And there are plenty of other activities along the way, some of which can be planned more flexibly (such as visiting colleges, meeting with counselors, and enrolling in test prep).
A good way to stay aware of these activities and other deadlines would be to like our Facebook page. We'll be sharing current information and insights all year!
