Expect to be there for about 8 hours (like a fill day of work). If you add up all the testing/break time, you get:
95 minutes (Chem/Phys)
90 minutes (CARS)
95 minutes (Bio/Biochem)
95 minutes (Psych/Soc)
10 min break (optional)
10 min break (optional)
30 minute lunch (optional)
This adds up to 425 minutes, or 7 hours, 5 minutes.
Long story short, expect to start ~ 8am, expect to be leaving by 4pm, latest if all goes normally.
Good luck!
