Three stars feels about right.  There are a lot of prompts here, I'll give them that.  However,  a significant portion are very basic or repetitive.  I found maybe 20% truly useful and unique.  The organization could also use some work; it's a bit of a mess to navigate.  It's not a terrible value for the price, but don't expect miracles.  You'll have to sift through a lot of duds to find the gems.
