Whenever I try to study math/homework, I almost always get a huge headache after 2-3 hours
I am unable to think/understand anything I read during this time, and is forced to take a 30min-1hour break just to relieve this stress...
Is this normal? I see/hear some people studying for 6+ hours straight without any impairments whatsoever.
When I took my SAT in highschool, it happened again at the last 2 hours of the exam... It was soo bad that in the reading comprehension section, I couldn't "read" anything... needless to say, i did horrid on SAT (the last 2 hours)
