You should generally expect to score in the same range as your practice test scores from about 10 days out. It's not typical to people post large score improvements in the last 7-10 days. So if your goal is higher than the low 600s, you should postpone your test.

Poor performance in DS, I am able to solve most of those questions correctly later
How's your timing on quant? I talk to people all the time who tell me they're not good at DS, and then we look at the data, and they're actually fine on DS when they spend the time - but they're spending extra time on PS, so they have to rush on DS, and then that kills their DS performance. Could that be happening to you?
