It will certainly have an impact on those who just annihilate the question banks as their sole method of studying. If it's done well, I don't see a problem at all. I've heard they will only be for simple, numerical answers, nothing qualitative, like "Explain the characteristics of the Harmattan wind".
I remember about a decade ago when my old school decided to use an online programme for maths homework. The software was absolutely terrible, the quiz marking system was sensitive to spaces, upper-case letters, decimal places, and all sorts of rubbish. (If you wrote your answer as 1.2873, it would be wrong, as the computer only recognised 1.287 as the correct answer, etc). I'd hate to be the person who fails because you spelt "airborne weather radar" as "airbo
urne weather radar" or something like that!
