English Vocab Website
When I was little and learning English in school, they would let us practice and expand our vocabulary on a website called Free Rice, which donates ten grains of rice to people in need for every question you answer correctly. It starts out with easy questions, and then the questions get harder as the website figures out what level vocabulary you have. There's no penalty for getting answers wrong. If you are studying English and looking to expand your vocabulary, it's a fantastic site. I thought I would mention it and link it as a learning tool.
