No, this is not a 'pay as you go plan'. With a pay as you go plan, content is dripped to you with each payment. We find this doesn't work because you can only ever see a small portion of the program and it's hard to plan ahead and limits the learning context.
So, instead, we release the full program content to you, with unlimited access, upon receipt of your first payment. We do this in the good faith that you will honor your plan as agreed.
