Hi
sorry I did not see the post.
At this link which is in evidence in the menu bar above - this is a bit complain about the students, not you specifically sir, - that the resources are there. Just to explore the main menu bar.
That said here
https://gre.myprepclub.com/forum/shorte ... 33239.html you have specifically the way to calculate your score and the unfolding of the questions during the exam.
There is also the formula.
Nonetheless, you should take roughly 17/18 questions in the sections to sum up to 315, considering you will have a bonus.
But is is just an empirical calculation. The algorithm does not work strictly that way
