My personal opinion: it depends on many factors, such as time availability, and more importantly, how good your logic is. If you are very good at logic, maybe you can skip it. However, if you think your logic need improvement, then probably it's not a bad idea to try some difficult questions, like those in FF or LSAT. I didn't do FF myself. But I participated in some CR question discussions in this board before taking the test, and I believe some of the discussed questions were from FF (and LSAT). |
