Here is my OG 11 experience
DS - 111-155
inaccuracy rate 9/45 - really disappointing
moreover average time per question was about 2.1 mins
Some were wrong because of carelessness but most needed a carefull consideration of different scenarios - eg picking numbers.
PS. 201-249
inaccuracy rate 11/49 - really disappointing
Average time per question about 2 mins - most were wrong due to carelessness but some needed more attention and then I could have got them right.
There might be some instances where I got correct answers right even if I did not mark the answers conclusively, I think this mostly happens in DS. You think you are 95% right and you mark the answer, not wanting to spend anymore time on the question. Within such questions the accuracy is about 95% but those 5% could really hurt bad.
We also know that 25 % of the questions are experimental. From among the last 50 or so in the OG do you think most if not all could be experimental? also since most were experimental earlier some of the kinds could very well be good questions by the time we take the exam.
What is your experience guys with OG math last 50 or so ? I would also appreciate your plan of action - my plan of action is meditation

I need to stay calm and not look at the clock. Also there are some concepts that I need to work on especially the number problems and marking answers conclusively, it will take more time but atleast accuracy will more than compensate for those 2 last unsolved (randomly marked) questions. And again if accuracy is improved you will get that much harder problems as your 36th and 37th problem which will have a higher probability of being experimental anyway
