Esperanto - online tests

Hi,
I just started learning Esperanto and I am loving it.
Does anybody know some online tests?
I would like to gauge my progress once in a while.
Thanks for your attention,

So, you’re brazilian just like me. I think you should ask la Brazila Esperanto-Ligo (BEL) in the first place. Mi pensas, ke la tiel nomataj ‘online tests’ ekzistas; tamen, mi ne scias cxu ili estas liberaj aux ne por la gxenerala brazila publiko.

Dankon!
