You can't study 12 hours a day for five weeks, taking only two days off in the entire scheme. Well... you CAN... but you won't do well on the test. You'll be mentally and physically exhausted. Also, since you've blocked all your evenings for studying, apparently you'll be spending this time alone, with no contact with friends or family. If you have any hobbies, apparently you'll be giving them up, along with your health, because your schedule has no room for healthy home cooked meals or workouts.
Remember even God had to rest on the seventh day.
