Learn Russian additional material?

Hello, I've been attending a Russian course at my technical college since this school year and have noticed that the pace is very fast. This is because there are about 26 students in the class, and 6 of them (including me) have no knowledge of Russian at all.

I'm currently learning Russian cursive writing with a writing trainer and print writing with Duolingo. Do you know of any apps or websites, preferably free, that can help me improve my vocabulary and general language skills?

Thank you in advance. 🙂
