Constitutional Law Exam: Am I a Khalbili?

Mujhe lagta hai ki main hamesha hi Khalbili (idiot) raha hoon. Exams mein 3 din bachhaye hain aur main yehi soch sakta hoon ki kya maine Constitution ka Article 368 samajh liya hai? Maine yehi socha tha ki Article 368 ka matlab hai Constitution ka amendment karna mushkil hai, lekin abhi tak main thoda confused hoon. Kya yeh Article 368 ka implementation ke liye jaroori hai? Kya yah Article 368 ka koi relationship hai Article 21 se? Exams mein yeh sawal puchhenge ya nahi, main yehi sochta hoon.

(I hope someone can answer these questions before I go mad!)
