Is there anyone ever try the PR's online free GMAT test? It is quite fun! there is a fuction that you can choose to show the score after answering every question, then you will see how the CAT judge you score...
both Q and V section start from 28. if you answer the first question correctly, your score will go up.
for example, I correclty answer the first 16 questions of Q, and at the moment, my score is already up to 50. but the 17th question I make it wrong, the score goes down to 48. and it will be difficult to go up again unless you answer the following questions continuously...
and my V is alwasy bad. I did the first question (SC) correctly and the score goes up to 31. however, the second question is RC (my weakest part of GMAT), the question is about the main idea of the passage. but I did it wrong....and you know what? the score goes down form 31 to 23.....my god...such a big penalty!
I think the real test is similiar to this. anyone ever try this?
