Exam season is always a stressful time for students and every time it comes around everyone prepares in their own to make sure they can perform their best, even if it means taking performance enhancing drugs. There’s a prescription drug called Modafinil that can enhance your concentration. Personally I've never heard of anything like this till yesterday, the only drug I heard of at exam season is caffeine pills. Loads of students would take caffeine pills at exam season to try and stay up and revise or pull an all-nighter the day before the exam to cram in as much information as possible. But sometimes that didn’t end up well because some students would end up taking too much caffeine pills and faint during the exam and subsequently need to be hospitalised for overdose.
