Well, I’ve been a participant in the TCS IT Wiz for the past 5 years and I have a decent idea of how to prepare for the TCS IT Wiz. You must read up on tech blogs like Geek.com, Arstechnica, Gizmodo etc. (It’s quite fun really). Another thing would be to go through Wikipedia articles of companies, codecs, anything related to tech. Make a PPT of that knowledge and write it in brief there so that on the day before the quiz, you can just revise quickly. Go through the booklet that TCS gives you and Google every damn term.
Well that’s mostly it. Preparing for this quiz requires patience above all.
Also, I’m gonna upload my very own archives. They can be found here.
