Hi
eaat bbSorry but I do not have access to OG on mba.com, I prefer GMATCLUB OG directory. However if you are having difficulty on finding link or question no. I would recommend put a question text starting 5 6 words in excel,date of attempting that question,section(ps ds etc)type of question(number properties strengthen etc) in this way you can maintain the
error log. Write a detailed reason of faltering, categories then what type of mistake it is(check gmatclub
error log).
Hope this helps
