Just learned about Partition Boundry testing while studying for my masters, and in simple words; it makes so much sense :) After learning, it feels like it is the most intuitive thing to do, but before it wasnt :) So I believe this should potentially be one of the first things any tester learns !
On top of this Category Partition method makes things more systematic so again in my opinion should be reviewed as well by every tester.
Wont get into details now but just google them !
