General question about sorting/searching on this forum - I am attempting to only work on one topic and Sub 600, 600-700 questions only. For example, I sorted on FDPs [https://gmatclub.com/forum/search.php?search_id=tag&tag_id=57] but I got a result set that included 700 level questions as well. I am not interested in solving any 700 level questions at this time. How can I filter them out? TIA for any help/suggestions.
Have you tried using workbook (click my workbook at the top of the page). When you start off, it only gives you the easiest questions and starts giving you tougher questions as you practice more and more
(and get better). This would of course not help if you are looking to do per topic work, but it helps give you tougher questions right when you get ready for it rather than just overdoing a particular difficulty level when you have already become good at it. If you are looking to practice one particular concept at a time, you would have to search using tags as you just did, but then for each question post, click 'show timer statistics' and it will show you the level of difficulty. Its entirely my own approximation (and I welcome all criticism and correction from anyone if it ends up helping OP) but for 600 and below, you want to attempt questions of difficulty 15-35%, for 600-650, try questions that show 35-65% on difficulty meter, for 650-700, try 65-85% difficulty questions and lastly for 700 above, try questions 85% and harder.
