Re: Oral puzzles
Hi;
I have an answer but I am not sure about it at all. Should wait for ganesh to verify it.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.

Re: Oral puzzles
The reason I failed oral math-couldn't understand the question. Well, not failed, but a 97% is pretty bad.

Re: Oral puzzles
Not a special course, but a sub-classification under math.

Re: Oral puzzles
And 97% is a failure? That does not leave much room for improvement.

Re: Oral puzzles
3% is a lot. Basically for me anything less then 100% si a fail, maybe cause I never got anything lower then that in my life, except in oral math and art.
