With your finger , remake the course on the floor , with your eyes closes . And , on the course , during the jump , think now for the next jump . But it's sometimes problem when you begin do jump . I remember , for my first course , I have the same problem and I jump the wrong jump xP
With a bit of exercises , you'll can do make a clear course! . I think , if you can , work the jumping course at home ! :) Good luck !!!
