As a professional writer, I pride myself on my spelling and grammar skills and I don’t like it when I catch myself making mistakes. The best way to be a good writer is to be a reader. I’ve never worked very hard on being good at spelling and grammar because the skills come naturally to me because I’ve been a voracious reader for my entire life. So my best advice for folks who want to become more skilled at writing is to read more. And that also goes for trying to learn a new language. Read as much as you can in the language you’re studying and it will definitely make everything come together much easier for you.
The test below is tricky because some of the words are very similar. I admit I missed a few of these questions, but I’m determined to try it until I get them all correct. And be advised: they’re not that obvious. Some of these I just knew I had correct but I did not. Good luck!
