So when you're in a climbing gym you're going to see lots of tape spread out all over the walls. All those pieces of tape are marking specific climbs, and those specific climbs are designed to start at the bottom of the wall and extend all the way to the top. The grading is different for whether or not you're climbing a route or a boulder problem.

There are two scales that you'll typically find in climbing gyms. When you're bouldering most boulder problems are going to have what's known as a V-grade. The V stands for Vermin. John the Verm Sherman is the gentleman who invented that systtem. Started down in Waco, Texas. There's a big bouldering area there called the Waco Tanks which kind of gave birth to the V-scale as it's known.

Bouldering grades begin at V0 and go all the way up to about V15 or V16 right now. Pretty substantial difference in the way each boulder problem progresses and the difficulties between a V1 and a V2, and a V2 and a V3. Also very subjective when you're dealing with how to grade a boulder problem. Everybody climbs differently, lots of different body types, lots of different route setters.

So, although the grades should give you a pretty good idea about which climbs are harder than others, don't ever be deterred about falling on a certain climb and then trying something harder because you fell on an easy one. Try all of them, and try everything that looks fu.
