You think studying for your high school exams was tough? Just be glad that you're not a high school student in China, who apparently have no time for basic needs like sleeping and eating:

The pictures recently posted on Chinese microblogging site Sina Weibo allegedly shows students studying for their National College Entrance Exams while hooked up to IV drips containing an unknown substance. The photos are said to have been taken by a high school senior from the city of Xiaogan.

According to the Ministry of Tofu, after contacting the director of Office of Academic Affairs, it was revealed the mysterious substance is in fact "gao kao," a subsidy for animo acids which are administered by the school's infirmary. The reason why these IV drip sessions are done in the classroom is to help students save time from having to travel to the infirmary.
