The Freshers Tasks are not out yet.
For now, we suggest you to do some basic things like:
CS-50: Watch the lectures and complete the problem sets (especially if you are relatively new to Computer Science)
Dual Boot Linux in your laptop (Ubuntu/Kubuntu is a good choice to begin with)
Start using Linux and get used to how it works. Learn some basic commands.
Try doing Bandit
If you're done with all that, you could have a look at the previous year's task doc in the Archive and attempt some for fun ;)
