See First for RMO, be precise with Rearrangement inequality, AM-GM and cauchy scwartz. The Trick lies within Seeing the problem and analyzing it various forms. Well All the Best for your exam.

I don't think that rearrangement is required for RMO, AM-GM and CS are enough to handle RMO,if you use them smartly.The main thing in inequality problems is to shape the inequality into a obvious AM-GM or CS form.And Angel's form of CS is also very very important.I am also giving RMO so all the best.!!!
