Wanted to share a link I came across on the Web. It's a 400-question archive of Tata Crucible from year 2006 to year 2009 (the page has many downloads, so look for the download titled 'Best of Crucible'). You'll need to make a Twitter / Facebook post to get the download link, but it's worth it!
 
For more recent content on Tata Crucible, check out our Singapore Campus edition 2010 archive. Rohit Nair's quizzing.in website is also an excellent resource for Crucible archives and news (as for other college quizzes).
