Try the following code.

//the input string MUST look like: "Exam 1: 10 11 12 99 88 14;"
int sep_index = input.IndexOf(':');
int terminator_index = input.IndexOf(';');
int exam_number = int.Parse( input.Substring(5,sep_index -5));
var data = input.Substring(sep_index +1,terminator_index-sep_index-1).Trim().Split(' ')
             .Select(s=>int.Parse(s));
var average = data.Average();

You can start from there and make it more robust
