ISI/CMI Unofficial Solutions

I've seen people claiming multiple times that they have solved 5-6 problems in the UGB section of ISI. CMI Entrance is genuinely harder, but even there people who often claim to have solved 4 problems but end up only getting partials in them.

Here's a link to all the blog posts and the unofficial solutions which I've prepared by myself. Note that, these have been made completely independently by me and has nothing to do with ISI and its professors.
