If you signed up with the Essay, you’ll get 6hrs total (5hrs if you didn’t sign up for the Essay).
You’re allowed to break up the 6hrs any way you want. For example, 2hr 30mins on E, 30 mins on M, 2hrs on R, 30mins on S, 30mins on Essay. I don’t recommend that breakdown, but I exaggerated so you understand that you can do whatever you want with those minutes. Break up the time according to what works best for you. Maybe you need more time in Reading, so dump more minutes there. Maybe you’re great at M, so use less time there.
Once the clock starts, you can’t stop it. You can take breaks, but the clock will keep running. So don’t waste too much time taking breaks.
Once you finish a section (like English), you have to notify the proctor. Then you start the next section (like Math). Once you finish a section, you cannot go back to it. So make 100% sure you’re done with a section before you move on.
Take a watch that counts the hrs and mins. But it cannot make any noise. If the proctor hears a beep, he can dismiss you and invalidate your test. If you have a watch that makes beeps when you start it, go on YouTube and watch a video on how to disable sound. (It involves opening the back of the watch and putting a piece of tape inside. It’s pretty easy.)
If you test on Saturday Feb 6, you will take the same test everyone else is taking. You will probably have 1-4 other students with you in your room. Not many.
You’ll get your scores on the same day everyone else who tested in the same school as you (unless there is a problem with your test).
