So, I took the GMATPrep official practice test and scored a 410, which is too low from my average test score of around 640. I am not sure what would explain this low score but there was an issue while I was doing my first section (Quant). The issue was that because of heavy lightening and rain, the power supply of my area went off, and it only came after around forty minutes. I then rushed to my screen but it was stuck, and after waiting for a minute, I refreshed the page. I was taken to the home screen and I clicked Test 3 to start again. However, rather than starting afresh, I resumed from the question I was at when the power supply hadn't went off.
Could this explain my Quant score of
9 (which is horribly below my average quantitative score), given that of the first 15 questions that I did, only two were wrong? I was really put off after the power supply was restored and my performance was definitely hurt because of the extra nerves I felt once I resumed taking the test.
