Here is a list of the flaws:
1. Normally, when I want to study verbal questions I select all unanswered verbal question and then go to random and exam mode. This however means that all questions are random - including all reading comprehension questions. This is really annoying, all RC questions for one passage should always come together.
2. Another problem when I chose the random and exam is that when I only want to do 20 questions, I have to answer 20 questions and then click 'finish'. This means that the 21st question is always wrong, this negatively influences the progress report. So, it should be possible to chose option from the normal and from the advanced settings. For example, only 20 questions, random and exam mode.
3. There should be a overview over all available questions, this will make it easier to find questions, even those that one have been correctly anwsered.
4. I think that it should be possible to us the question as a third or maybe even fourth GMATprep test. I dont see why not, it would also attract many new costumers.
Hope this help, Lars.
