I think it's always a good idea (no matter how slow or fast you are) to save parallel reasoning/flaw questions for last. These problems are not only a time drain, but some of these problems require too much effort, and they can have an effect on how you approach subsequent problems.Also, never waste too much time contemplating between answer choices, even if you're striving for perfection.If you can't see an obvious answer choice the first time through, either take a quick look at the conclusion of the stimulus, look for degree words, or just move on and return to it later.The above advice will help assuming that your problem is due to poor time management.However, if you're a slow reader, then I advise you to just practice -- a lot.Remember, there are a limited number of logical problems in the world, and your speed will be highly dependent on your familiarity of these problems.When I first started, I was barely able to complete a LR section. After practice, I'm now finishing with 5+ minutes to spare. So I have no doubt that you'll see similar improvement if you put in the effort.
I'm having trouble completing 5/6 questions on the LR sections, what is a good way do you think to pick up spead?
One question though - do you skim through each and every question in that section before you answer any of them in order to see which ones you will answer first or do you have some other approach?
Eliminating answers...allows me to move through questions much more systematically. There are flaws repeated over and over in various answer choices (the passage says some while the answer says most or all, for instance)that you can become better at identifying as you go.
