I do not call it "hard" as far as materials and written tests go. Even the in water time is not "hard" as such, but it can be a challenge. The class is a practical exercise class. It is a thinking and performing class, as various scenarios are played out. It is a participation class. You need to be in the middle and a part of everything- no sitting in the backround, getting by. You should have a real positive attitude about it and be excited about participating. I think the hardest part for our students is the time we have them standing around waiting for something to happen. They have to stay alert and observant, and then think, plan and act when something does happen ( and it always does). That can be hard. The course properly taught also requires indivdual initiative and sometimes innovation. It is a great growth step. Take the class not to get the certification, but to learn things that will serve you well as long as you are diving. When that is your attitude, dive in!
