To add on the initiative, I would like to highlight few points.
Currently, I am engaged with SC/CR questions of the QP1.
In my opinion, the SC questions are very easy with just 5-10% of the SC questions lying on the 700-800 level.
However, the CR questions may give you an impression of the same difficulty as the case with difficulty level of last OG questions.
But, since you get a software in which time will kill you, this should be a premium buy for those considering practicing more official questions.
