Mmm... I don't think 12th board exams r easy... Cuz, sometimes u can't always prefer the toughness of questions but also how much time a question take .... Exam idea pretty much have all exam type questions but the the toughness of the syllabus is something else specially when u enter 11 from 10 .... The syllabus become extremely vast... Specially physics and chemistry.....
Ohh but I didn't took science as my stream I took arts it's convenient too read and good course understable my 11 class was best I don't know why but I scored more than average it was pretty good to be good student , even while I read mangas right before exam night till 2 am lol. And about 12 th class board was pretty tough for history but as for all it was normal 10 boards is pretty much easy going if u study best since I was bad at maths i didn't get good grades.
Sometimes i wonder what my future is gonna be when im asking questions on a 2d pornsite when my board exams are just a little away (● ̄(エ) ̄●)
