If i have SortList and i want to save 10 object with the best result how can i do it?

private void InsertThisStudent(Student std, List<Student> List)
     {

         for (int i = 0; i < List.Count; i++)
         {
             if (std.CompareTo(List[i]) < 0)
             {
                 List.Insert(i, std);
                 return;
             }
         }
         //If this is the last one
         List.Add(std);
     }
