Does anyone have the update for Dr Collins, I just mailed him today and it seems like its costs additional 20 dollars and I was wondering if its even worth it to purchase it. Is it new material?
Also I have been hearing that Dr Collins is not good for math. Are there any suggestions what else to use? What about reading, any other materials used?
Thanks
