I would say believe in yourself. It will work for you. That is one of my favourite horses.
You might try relaxing and doing the mantra without the book. This should work. Then do it with the book in front of you. Then do it with the book upside down and flip through the book backwards (in photo-focus).
Come back and lets us know when the concentration breaks down or if you maintained the state for each of the three tests. Do each test for about 3 minutes or until you reach the end of the book. It doesn't have to be exactly three minutes so don't time it.
If it helps, I know you Can do the whole system. 
Good luck,
