Be confident . Even if you are not prepared well.
Never show that you do not fully learnt. Knowledge doesn't matter unless you have a good presentation. Present exam as if you are a guy and you have to impress your love.
Many things happens without a reason. You may pass wiithout prepration. And as per my personal experience maximum exemptions and minimum failures are in accounts.
Take exam like a BOSS. Me too got exemption in Nov. 12 without full prepration.
