At the point in your form that you determine whether to continue to ‘skip to the end of form’, put all the subsequent questions inside a group, and put your skip logic on the relevant property of that group. As a consequence, when you want to skip, all the following questions (which are now in the group) will be hidden, basically immediately bringing up the end of the form.
Its good to remember that you never actually skip to something; rather, you hide everything in-between
