TCS IT Wiz, the country's most prestige and biggest IT quiz event, is an annually organised IT quiz by Indian IT giants TCS. Winning it has been a dream for many. It has been for me too and is still. This quiz changed my life. It made me what I am today - a techie, tech geek or tech savvy or whatever you like to call. Only to prepare for this quiz, I started Tech Biscuits back in 2012 and that too during my school exams.
Enough of dud talks. Let's back back to the point- 'How to prepare for TCS IT Wiz'. The best way is to read tech blogs daily. Also search for funny IT facts because these are asked often. If you can give more time to preparation, then better buy Blitz The IT quiz book. Here is the link. Contact Raveesh Mayya, he might as well give you a discount as he is the author.
For the @TCS round, just go through official site of TCS and learn more about it from there only. Keep your tech quotient up to date and keep reading Tech Biscuits
