For PMP exam takers, 2020 is an interesting year. The COVID-19 impact has forced PMI to open the door for online proctored exam, so you no longer need (but can still choose) to go a test center. The looming change of format, however, has been a major source of frustration…


The GOOD

Value

The first thing I want to compare is the value: how much money do you actually need to spend for typical EV3 activities.

The EV3 has two versions, the “home” edition sells for $349, and the “edu” versions is listed at $439. Why the significant price difference? Apart from different…
