As already stated, try one wake jumps first. Practice the progressive cut. Swing out wide, then when you feel the boat start to pull you back to center, begin to lean on your heels to start your cut. You want to "progressively" edge harder towards the wake. In other words, your fastest point should be AT the wake. When i say fastest, that doesn't mean you have to be going super fast, it just means that you want the wake to be the point in which you are traveling the fastest of that particular cut.
Make sure to keep consistent pressure on the line. That pressure should be increasing as the cut progresses. Once you get to the wake and the board begins to edge up it, you want to straighten out your legs, resisting the forthcoming "pop". Don't absorb the wake with your legs. Also, don't fully lock out your knees. Use your hip and leg muscles to remain stiff. Stand tall.
The timing is the next big issue. You want to be standing tall AT the lip of the wake, centered on your boards rocker or pop point. As you pop, ensure the handle remains low, near your waist. Look up at the horizen or towards the shore. As you start to come down, spot your landing and be prepared to now absorb the landing with your knees.
Ride away stoked. You should start small as suggested before, jumping one wake first. Pop will get you across the wake, but you need to build that first. Don't worry about clearing both wakes at this point. Make sure on your cut, to keep the handle in front of you and close to your body and waist. Don't let it get pulled to where your arms are fully extended in front of you, that will cause you to get pulled forward.
