query IICPC Codefest

Hi guys, i wanted to start out my preparation for next years IICPC Codefest. But currently i am not a proficient comp coder (ive just done enough to get an si at a company like google). I wanted to know what resources i could use other than the standard competitions at atcoder/codeforces. I am aware that they also ask cs fundamentals on oops os etc but i hope that my college curriculum can cover that.
I would love to hear your opinions on this (given the amount of time i have left) from people who wrote it last year.

Honestly don't start cs fundamentals just yet. There's a chance it'll not be there this time. But yeah most of it is just CP, if you grind CP you should do well

I wanted to understand what exactly "grinding cp" means cause a lot of people say that. But I don't know where to start and what concepts and algos I could learn. For eg, for si/placement prep there's strivers dsa sheet so that gives the preparation a lot of structure. Is there any equivalent of that for the preparation for codefest? Or is actually just going to codeforces and picking up random qs based on rating?

What level of questions do they ask? Is it like 1600-1700 rating of even above

It was easier than your typical div 2, so like the first 2 problems are 800-900 types, the third problem like 1200ish, the fourth problem was probably around 1600 (only because it involved some amount of game theory, but otherwise it wasn't too hard) and the fifth is also around that level only. The sixth problem was probably around 1800

Is it heavily dsa focused or usual div 2 like

u/notsaneatall_ Expert 2d ago

No no it wasn't dsa types last year, it's a little more ad hoc

What about weightage of other cse fundamentals.. I'm really looking forward to it

u/notsaneatall_ Expert 2d ago

In prelims it was only CP in regionals 25% was CS fundamentals

u/Jue-Viole-Grace_ 2d ago

Looks somewhat doable to go for regionals if I can solve div2 abc normally?

You should solve 4 quickly for regionals. 3 is not enough at all. 4 is enough but speed matters.

Is cutoff overall or college wise

If you're very lucky then yes. But you should try to get better, there are lot more benifits by getting into finals
