GMAT OG Tests Mistakes VS Score

Question

Hey everyone,

I have a question about the GMATPrep software's accuracy with regards to the number of mistakes I can make. I know the test's adaptive and there's no exact formula. But I feel it's super inconsistent. Paradoxically, my overall score has been remarkably stable around 770.

My scores and mistakes are in the attached pic.
In Quant: I've made 6 mistakes and got a Q51!! Definitely an outlier. Then again 5 mistakes for a Q50 and 4 mistakes for a Q49...
In Verbal: 1 mistake got me a V47 and V48. 1, 2 and 3 mistakes got me a V47. V49-50 seems impossible even with 1 mistake...

Is the actual GMAT scoring similar to the Prep? How many mistakes is it safe to do for a V47? My Test 6 score has semi-freaked me out. Giving the actual exam next week. Is the actual exam's difficulty and length in line with the GMATPrep tests? I finished all the verbals' at the absolute last minute, except Test 6.

Thanks in advance!

Your curiosity to know the algorithm has been very common among test takers; However, in my opinion and based on some desktop research, I can assure you there is no complete understanding of the algorithm that GMAC follows.

You have scored highest in your practice test i.e 780 with maximum number of mistakes; seeing historical record of your attempts, I can only say you have been consistent and the scoring quite depends on the level of difficulty of the wrong option that you choose.

There is a range of score that algorithm can match based on your performance and in isolation to the difficulty levels and patterns of right and wrong it is not fair trying to analyze the algorithm

V49-50 seems impossible even with 1 mistake...

The Verbal is quite steep at that level. I got 1 incorrect counted question and saw my Verbal drop to V48.

All the best.

GMATWhizTeam  thanks, will check out the video later tonight!

gmatknightDOTcom  wow that's harsh. I'd be really happy with a V48. Currently doing all the GMATPrep 600+ SC questions on the forum, to cover the ones that didn't show up in my practise tests. I usually get all the CR & RC correct, so far have got max 1 RC wrong/test. It's the SC that tends to be a bit random, specially if it's an idiom question I haven't seen before or a long complex one while I'm screwed on time. Thanks for your reply.

What matters is not only the number of questions you get correct or incorrect but also the difficulty of the questions you get correct or incorrect.

For instance, if you get three easy or medium questions incorrect, your score will be lower than it would be if you got all the easy and medium questions correct and three hard ones incorrect.

So, one takeaway is that it's important to be careful to avoid making careless errors that result in your getting easy or medium questions incorrect. It's one thing not to figure out how to arrive at the correct answer to one of the hardest questions, and another to whiff a medium one that you could easily have gotten correct if you had been more careful.

Hey MartyTargetTestPrep , thanks for your reply. Makes sense - my last practise with the 1 mistake that got me a V47 was a relatively easy RC. Worst part is that I kind of knew I was wrong immediately after I pressed confirm. The obvious answer felt like a trap and I made up a 'convoluted story' to justify the other option. Well, the silver lining is that now I'm aware I'm prone to do this and will try to avoid doing so on the actual exam. You've given me great advice on the TTP chat as well and I've gone through your debrief and most of your blog. Thank again!
