★★★★★Mar 15, 2021
Wrong math

The answers are not correct on most math questions. Most are wrong with just the first table where you bring the depth and time together making the pressure group.

★★★★★Mar 5, 2014

★★★★★Aug 30, 2012
Wrong!

Many of the questions are confusing and/or have multiple correct answers.

★★★★★Apr 13, 2011
There is a wrong answare

I'm a PADI Open Water Scuba Instructor often using the PADI RDP in metric system. Solving the RDP quiz in meters, I found a relevant dangerous mystique. The question is: "Your first dive is at 16 meters for 50 minutes. After a 20 minutes surface interval you dive to 16 meters again, how long can you safely stay at that depth?". 16 meters for 50 minutes = Q Q after 20 minutes = M M at 16 meters = NDL of 33 minutes The correct answer should be 33 minutes or less, but the app is considering 35 minutes as the best alternative, what may put the diver in risk. Please, take a look at the surface interval. 20 minutes makes a Q into a M, not a L as the app is saying.
