Gmat Paper Tests Scoring

I bought some of the official Gmat paper tests (link for these tests at bottom of post).

I am somewhat confused about how to figure my score. For example, I just finished Test 48.

For the Verbal, I got:
Correct: 44
Incorrect: 10
No answer: 2

For the Quant, I got:
Correct: 46
Incorrect: 5
No Answer: 1

Total:
Correct: 90
Incorrect: 15
No answer: 3

Maybe it's just me, but the 'Scoring Information' section on page 32 is confusing.

I believe my corrected Raw Score for V is (44-10/4)+.5=42, which I believe translates into a Scaled Score of 38 (according to page 30).

For Q, my #s are (46-5/4)+.5=45, which I believe translates to a Q Scaled score of 46.

Now do I add the scaled score of 38+46=84, which looks like a 670??
Or do I take my total #s (90-15/4)+.5=86, which looks like a 680??

I really am confused here - has anyone figured this out yet?

Thanks in advance...

Use your Total Corrected Raw Score to find your Total Scaled Score. On the whole test, you had 90 correct and 15 wrong, giving your a Total Corrected Raw Score of 90 - 15/4 = 86.25, which rounds to 86. According to the conversion table, a Total Corrected Raw Score of 86 corresponds to a Total Scaled Score of 680.

Thanks for the responses Bob and scorpion.
