        • Question with a error.

          In the following question, line 18, there is an error:

          - this.wingCount = 0. wingCount don't inherited by Animal class, because it's a private member in Creature. So there will a compilation error.

          1. What do you need to do to correct compilation errors? (Select two)
          2. public class Creature {
          3. private int legCount;

          • Click on first wrong answer displaying empty popup

            When I finish My Test and if I want to see what and all wrong answers I made, for every first wrong answer it's displaying empty popup...then if I click on right answer and go back to the wrong answer...that previous opened answer remain in that position

            • "Forgot password?" button missing

              In the login form there is only a "Sign in" button, not a "Forgot password?" button or link is provided...it would be very useful to recover a forgotten password or reset an old one. Thank you

                • Be able to cancel a test if already started.

                  I accidently started a 210 min test and I really dont have time with that now! Possibly tomorrow. There should be a way to "quit" the test.

                                  There are 2 typos in the same question. See, this is VERY distracting.
                                  I'm evaluating the test online, but would never buy this test tool now.

                                  The feedback link 'Report a bug' leads to this suggestion page. That's odd too.

                                  ---

                                  #1 - Give a piece of code. What is true?

                                  #2 - Reversing the ofrer of o.wait() and o.notify() will cause this method to complete normally.

                                        • Selected number of questions

                                          It would be better if the user can select the number of question, and depend on the number of questions selected the timer should adjust.
