Help UK Indoor Climbing Grades???

The climb gets harder the higher the number - 1 is easier than 5. It also gets harder the higher the letter - A is easier than C. For example, 1C is easier then 2A, which is easier then 2C etc...

5a is easier than a 5c, 6a is harder than 5c. The number indicates the major rating and the letters indicate additional (finer) rated difficulty. The scale is below: http://en.wikipedia.org/wiki/Climbing_grades#Comparison_table The rating on a route is always indicated for the "crux" - the most difficult part of the climb. There may be only one 5c move on the entire route, but it is still rated as a 5c. Sometimes they will use a one to five star rating to indicate the consistency of a climb, especially in the YDS rating system: 5.9, 1 Star - Much of the climb is easier, but there is a 5.9 move at the crux 5.9, 5 Star - Almost every move on the climb is 5.9, consistent and harder Good Luck
