Wondering about SAT timing

So, I'm scheduled for an upcoming SAT. I'm slightly worried and want to plan my day well. Can someone tell me what time the SAT test usually starts?

The actual start time of the SAT can vary slightly from test center to test center, but typically, check-in begins around 7:45 AM. The College Board highly recommends that you arrive at your test center no later than this time to ensure you have ample time to check-in and get seated in your testing room. Once all the students are checked in and seated, there will be some initial instructions and preliminary setup procedures such as filling in personal information on your answer sheets.

Actual testing generally starts between 8:30 and 9:00 AM. It's difficult to predict an exact start time, as it can depend on how quickly all the students are checked in and seated. Do remember to bring a valid photo ID and your admission ticket, and it might be a good idea to bring a snack and a bottled beverage for the break as well.

I strongly recommend you to have a good breakfast before you head out, and to ensure that you have a good night's sleep the day before the test. And, of course, don't forget to bring your #2 pencils and a calculator that complies with the College Board's requirements.
