It actually means: "How long have you studied Japanese?

Dono kurai or gurai is a question word that means "how long" or "to what extent," etc.

Benkyou shimashita is the past tense form of the verb benkyou shimasu and it means "study."

."

Ah, honto desu ka? I'm no good at the past and future tense. Still learning the present
I decided to learn japanese last year, and I have been studying since then. I don't attend a japanese language school but I am looking for one. I learn mostly from podcasts, web pages and books. I don't know how to say that in nihongo.

I'm going to try a sentence.

Kinou wa watashi no zasshi kaimashita. Zasshi no namae wa KERA desu.

I'm not exactly sure how the structure of past tense sentences go, but hopefully I got the verb right.
