Well, I’ve just stumbled upon another fantastic free resource, offering comprehensive instruction on the subject of grammar and English usage. It’s an online training course provider called Alison and you’ll find it here.
There are a whole host of individual free courses available, from IT and mathematics to chemistry and economics. The course you’re likely to be interested in is called ‘English Grammar Rules’ and it is described thus:
“This free online course offers a comprehensive revision of English grammar. It is designed for those already fluent in English, but who want to improve their writing. It covers punctuation and grammar, from commas and colons to adverbs and prepositions. By completing this course, you will see a marked improvement in your written English. Each section breaks down the rules into easily assimilated explanations. There is a section on spelling. This course is ideal for anyone looking to improve their written and indeed spoken English.”
All you need to do is sign up (which is free) and go here. Then, one push of a button and you’re off.
I really can’t recommend this highly enough for those of you who feel their grammar skills may need a little bit of an overhaul before they attempt to embark on a proofreading career.
Best of luck.
