I am just starting to prepare for my GMAT, getting all concepts cleared. I have a question though.
How often do "Perpendicular Bisector" and problems based on complex sequence rules come in GMAT. I am not sure if I should spend time preparing if chances of getting these problems in GMAT is rare.
I am aiming for 700+ in GMAT and want to prepare for all required concepts. Please advise.
This kind of question is not rare, so I'd recommend to learn it. To be honest when I started I thought I'd never understand it. But remember each problem can be solved using basic principles of algebra and geometry. Check http://www.gmatclub.com/phpbb/viewtopic.php?t=45587
I posted some good material that can help you understand most of the principles.
