I finished my CB exam about an hour or so ago and I must the experience is nothing to compare to paper based. It has so many advantages over it.This is exactly my feeling. I gave both Paper based and computer based exam. I felt much comfortable and confident with CB IELTS. But turns out, results for CB exam were disappointing. Felt like they were intentionally giving lower scores. Apart from scoring 6.5 in writing yet again(inspite of writing what seemed like my best essay)..specially my speaking score decreased to 6.5 band that never happened in my previous paper 2 based attempts in academic and general when I scored 7.5-8 in speaking. I remember on test day, felt like it went on par or even better than previous attempts.
Finally, only got success with paper based IELTS. So I have my doubts on this mode of test. Why spill our hard earned money on this meretricious IDP Computer based IELTS test. Go with tried and tested Paper based., If possible go for British council option they are better trained evaluators. Just my two cents.
Regarding the marking computer vs paper, speaking has not changed one bit so I doubt it has any influence. It is the same face-to-face interview and same procedure as paper based version. Not a thing has changed in this module.
Anyways, doing the test over computer, no one really knows if it has affect on the result from the examiner point of view.
Did you go for revaluation on that result (CB)?
