Go For Gold

The Go for Gold Initiative was launched about a year after CodeChef was incepted, to help prepare Indian students for the ACM ICPC World Finals competition. In the run up to the ACM ICPC competition, the Go for Gold initiative uses CodeChef as a platform to train students for the ACM ICPC competition via multiple warm up contests. As an added incentive the Go for Gold initiative is also offering over Rs.8 lacs to the Indian team that beats the 29th position at the ACM ICPC world finals.
