From what I have seen in the site you mention the answer is yes, it is quite comparable in both type of questions and difficulty.
Nevertheless, I would say that perhaps what is more difficult in the test is when you really need to do the math right (meaning: you cant just estimate and make quick calculations given how close the answers are to eachother). In the tests I taken online vs the real one, some particular questions were quite calculous intensive (with multiplications and divisions of not easy numbers lets say) so make sure you get that part well covered!
Also, something that I never saw in the online versions of the tst is the interdependence of the questions. In the test I did in real life, many times you could not do Question 3 right if you had not correctly done question 2.
Industries covered can vary quite a lot, in my test there were 3 business cases, one was retail, there was airlines and energy as well... But unlike other tests, I felt the technicality/jargon of the industry was not a deal-breaker, at all. So in that regard, don't worry too much.
Best of luck to the test! :-)
