Hi,

I am an international student who is new to GMAT.

Thus, I'd like to thank this site which has given a lot of beneficial information as to GMAT.

I'd like to ask you a quick question.

After taking practice test on GMATprep, I got Q48 V18 which made me feel depressed.

Q48 is understandable because I answered correctly more than 80%.

However, I do not understand why V is 18.. Since 21 out of 41 were correct.

That means almost 50% I got correct answers, doesn't it?

Thus, I got confused why I did not get scaled score either 28 or 29 instead of 18..

I am not sure whether this is normal on GMAT..

Please give me a clue.

Thanks in advance!
