also, what do you mean surveys and tutorials?
When you sit down to start your test there's a 15 minute tutorial. It basically goes through how to take the exam, ie., move the mouse over the box and click it to make your selection, hit the "next" box to move to the next question, hit the "mark" box to mark this question... etc. etc. If you've done practice tests this should be nothing new. If you don't need the tutorial and you have something you'd like to jot down before you start this is the time to do it. For instance, I used grids to help me with the hole punching section of the PAT. I took about 4-5 minutes to draw 15 grids during the tutorial so I wouldn't have to scramble during the test. If you're good to go then just take a couple deep breathes and use the time to get focused. When you're ready hit "end" and your test begins. Otherwise, at the end of 15 minutes the timer starts for SNS and you're off.
The 1st part of the test is SNS (90 min) followed immediately by PAT (60 min). The timer runs continuously throughout this 2 hrs 30 min. After the timer runs down at the conclusion of the PAT you're allowed an optional 15 minute break. Again, the timer is rolling during this 15 minute break. You can either use this time to grab a snack out of your locker, use the bathroom, and or you can continue at any time by hitting "end". Whether you opt to wait or continue is entirely up to you. But, as soon as you choose either option, you're thrown right into RC (60 min) followed immediately by QR (45 min). After the time runs out for QR your test is over.
When you're finished a post-exam survey will then show up with another timer which allows a maximum of 15 minutes, or however long it takes you to answer the questions. For example, how was the prometric staff?, did your computer operate efficiently? etc, etc. Should take you about 5 minutes tops. Hit "end" when you're finished or wait for the 15 minutes to elapse and your exam scores should pop up with limited delay.
If you add up all these times the test could conceivably take 300 minutes, or 5 hrs. You're guaranteed a 4 hr 15 minute exam to complete all sections, but the other 45 minutes involve the tutorial, break, and survey. How long you take for those is entirely in your hands. Sorry if this post is a little long but I would not want to go into my test without this information and it appears as though you needed a heads up. Good luck.
