I read in OG that, in GMAT, leaving a question is more penalizing than attempting it wrong.
Say, in the quant section, within the stipulated time, I could complete only 33 out of 37 question. My sectional score was 47.
So, in last few seconds, instead of leaving the question nos. 34,35,36 and 37, I could have marked all "C" or any option of my choice and could have got score greater than or equal (in case all the guesses turn out to be wrong) to 47. Is this the case?
How does the scoring work in GMAT in case I attempt right/wrong/or No attempt?
