Based on this list(Top 500 Russian Nouns, here on Masterrussian), I made a couple of quizzes... for myself, but I thought I'd share the links with you, maybe some of you will find it helpful.
1 (1-50)
2 (51-100)
3 (101-150)
4 (151-200)
5 (201-250)
Enjoy!
(Planning on making the other 5 in the next couple of days)
