I'll give some advice that could help you to have a good result from this challenge.
What is the freeroll grind ?
The freeroll grind is a method of grinding where you play a lot of tournaments in order to get the required points to enter other tournaments in order to reach a high level.
The basic idea is to have a lot of small wins during all the tournaments, aim for playing a lot of tables and at the same time try to play your own game.
You must have in mind that it's going to be hard to get a good result if you don't follow this advice!!!the key points that people usually forget are$$ play cash games first and never do freerolls when you're in bad mood because it is obvious that you can't play at your best with a bad mood!!
