It is recommended that you avoid the use of the pedal entirely.

Let your ear be the guide.  Sometimes too much pedalling blurs notes in very fast passages.  Pedal Chopin, like you would pedal Mozart.

Jazz, you have just bitch-slapped every person who has ever performed the "Revolutionary Etude".

I agree that your ear should be the guide.  There is always going to be controversy over pedal markings in pieces.  Basically, go with what you think sounds best.  I've heard a few performances of the 10/12 etude where pedal is ommitted completely, but I found them much less appealing than the more common performance where pedal is used quite liberally.  To me, this etude is about a grand, sweeping sound that lingers and constantly changes form.  With such a dry sound, I don't think that it can give the same effect.  Too much pedal makes it sound murky and sloppy, but just the right amount (which is different for everyone) turns it into a masterpiece.

I agree with Jazz to the extent that pedaling in this study should be hardly noticeable.  Hence, I pedal roughly every half-bar.  I get a crisp sound, no "muddiness," and the comfort and power of the pedal.

It's going to depend on a lot of things. Is the room you will play in very resonant and how big is it??eg. Also how fast do you intend playing it? If you play it very fast even a little bit of pedal may be too much! as its a very notey / busy etude. There is nothing worse (there may actually be?!) than a really muddy rendition of the Revolutionary. If it's for an exam definately err on the side of caution and definately don't even let your brain skip passed the idea of allowing it to cover anything but the most exacting finger work. The difficulty of course is that it is a very sonorous piece and needs something to give it a sense of grandeur and scale but be carefull not to only rely on pedal to do this!! - I have known at least three college students play it  for exams and always the comments relate to use of pedal. All the Best!!
