Bouldering grades
Boulder Planet grades problems from 1 to 12, plus ungraded 'wildcard' problems. It says the 12-step scale bridges the gaps between V-grades for more gradual progression. Competition-wall problems are graded by competition category (Novice, Intermediate, Open). V-equivalents below come from one climber's blog, not from the gym.
