How to participate in Contest hosted by other organisation or university?

Hey friends can anyone tell me that whether i can participate in contest held by some other university or collage if yes then are there any extra procedures need or just like any other contest i can join ie just open the page and start solving.

Well codechef do not provide a timer for external contests(i.e contests held by other universities). You just click on “COMPETE” then go to “All Contests” here you will find all the ongoing and future contests. Regarding your participation in these contests as such most of them are open to all but only some requires registration prior to the contest , the description of that link is also provided on their contest page.
