This is a professionally guided/instructed class-
I'm teaching a Gear and Anchor Class for the Outdoor Adventure Club at Cragmont, in Berkeley this Sunday. (class info is here: http://www.outdooradventureclub.com/trips/rock-climbing/cragmont-gear-anchor-class.html)
The class is a full day, is hands on, and will provide the information and practice for you to be able to set up top rope climbs in a variety of situations, ranging from easy two-bolt anchors to more complex anchors built off of trees, boulders, cams and nuts.
You'll learn/review how to tie the following knots:
Overhand on a bight
Eight on a bight
Bunny Ears knot
You'll learn how to place trad gear, and how to critique gear placements.
You'll learn how to build two piece anchors, three piece anchors, anchors with four or more pieces, how to extend anchors and how to build anchors a significant distance from the climbs.
By the end of the day you should feel confident in your ability to build top rope anchors, even if this will be the first time you've tried.
The class is normally $119 to the public, but members of the Rock Climbing Meetup can claim the discounted member price of $99 for this class, saving $20. To claim the discounted price, just put the word "Meetup" after your name when you register.
Plus, everyone who takes the class gets a cordolette to take home so you can practice tying knots, and use it to build anchors.

Let me know if you have any questions, I'm happy to answer them.
