I have recently purchased the full pack from James. The slides are very very helpful and has saved me a lot of efforts of building the content myself. Now I can focus more on teaching that worry about putting the right content together for my students. Thumbs Up!!

Wow! I downloaded the free trial, and subsequently bought the full bundle. It is incredibly helpful, not just to deliver the content but providing example questions, step-by-step instructions for more complex topics etc. The exam questions and answers, as well as the worksheets included in some topics makes my life easier as well. Definitely recommended!
