instead of fixating on an actual number which doesn't really make sense in an adaptive test, why not work on your fundamentals first?
bro i know that the scaled score has got a lot of factors
as i got 36 scaled score with 11 mistakes and 35 with 13 mistakes
probably this is because i got 700 level questions wrong
but one thing is clear that for practice you need to know that how many questions you can afforst to get wrong
for eg now i know that i can afford 2 mistakes in SC and 2 in CR and 3-4 in RC for a 40 in verbal overall irrespective of the difficulty level
so while practicing i keep a note that my accuracy in SC and CR is not less than 80%
this actually helps me a lot to get closer to my verbal score aim
thats what my intention is
please help me if you can to get more insight
