Infinitely easier, but not as easy as CDP Keyholes and TFE. Achiever's Keyhole/TFE gets you to do them the right way while CDP lets you count lines. The right way being actually visualizing and manipulating the shapes in your head. Have you done the 2007 PAT? That has keyholes and TFE pretty close to the real thing imo (though the diagrams are terrible print!).
I kept getting 17s and rare 18s the whole time on achiever and got a 23 on the real thing so that gives you a quantitative way of figuring out how much easier the real thing is.
