I think you are worrying too much about what you can and can't do.

Move onto the next tape. As you go through the course, each aspect becomes clearer, and is explained in more depth.

You will photoread 2 more books during the course, before you even try other material. One of the things you are taught is "Notice It, Play with it, Stay with it" ie just notice the feelings you are getting and keep photoreading. As you photoread more books you will become more proficient and even find your own way of activating material (based on the teachings in the course).

Why not listen to all of the tapes once to get the general gist of the course, then start again. Alternatively, you can listen to a particular tape more than once if you do not fully understand the concept on the first pass.

Hope this helps.
