I think you have to do the flash cards multiple times to be effective. I've manually written out 1000 hindi flash cards. I would go through them a few times each day. I usually add a few of the older cards randomly, and I've had good progress over the course of a year. I think it was better for me to use that than Anki since I had to learn to write the devegnari.

I also heard finnish is a really hard language, so maybe it's that.

For speakers of European based languages with Latin character sets, learning to read and write Finnish isn't so hard IMO. It's phonetically spelled, and the character sounds are more or less the same as other European languages. The grammar is tricky, but literacy is simple. Or at least it should be.
