You should solve problems that are rated higher than your personal rating in a topic. The higher relative to you a problem is rated, the more your rating will increase if you get it right, and the less your rating will decrease if you get it wrong. When your rating drops below certain values or passes certain values you level up or down. Read about it here at the Levels page.

Note that as of now, if you level up or down midweek, then you will have to wait until the following week to receive problems of your new level.

No, of course not, that would be a really silly system. Your rating would still increase, though not by much. For example, if you are rated 2000 and you solve a 1000 problem, your net rating will be positive, but likely too small to register. This makes sense, because we don't gain much information from you solving a really easy question.

If you solve the problem 'instantaneously' (a short period of time), your rating would increase.
Having said that, there are extreme edge cases where your (net) rating might actually decrease despite solving a problem, especially if you only got it right on the third try. This could occur when there are gargantuan changes in the ratings (either your own, or the problem) over a period of time.

Note: It would be extremely difficult to work your way up to 3000 by solving tons of ridiculously easy problems. It would be more rewarding to work with problems whose difficulty suits you.

What if we solve problems with rating lesser than our rating, but answer them correctly? Will our rating decrease and will we be demoted?
