IMAC flies wind corrected lines. If the wing is not level and there is no wind for example pulling to a vertical line will send the plane into an angle dependant on the amount of wing angle. A very slight angle is used to advantage with a cross wind (upwind wingtip down slightly into the wind). Read Don's books Proficient flying and Crosswind flying for much additional information. http://www.donshobbyshop.com/

The track of the plane is judged and not the attitude of the wing. This can become quite confusing unless you realize the corrections are to be done with the rudder. (Most pilots bank the wing if the plane is coming in or out which results in a downgrade. This is from learning how to fly and not being instructed to use the rudder to correct).

As is said in my original post go to a contest. Practice the sequence before going and have fun. If you intend to fly then go ahead and join IMAC. Start getting the newsletter (which is now published in RC Excellence mag) for additional information. Do a search here on RC Universe. Doug Chronkite is a former IMAC president and has added quite a few good bits of information to questions.
