Terrific Tenses Course

Really understand the tenses with my in-depth course. Clear explanations and lots of exercises so that you can really practice and learn to use the correct tense without thinking when you speak.

See the table of contents for Terrific Tenses here.

Cool Conditionals Course

Maybe you've heard of the zero, first, second and third conditionals. But did you know there are many, many more ways that we can use the conditionals? I explain everything here, and I've also made you hundreds of practice questions so that you can learn to use the conditionals correctly and automatically when you speak.

Marvellous Modals Course

The modals! So many students (and teachers) hate them, because they have so many different meanings and uses. But they are very important. Learn to really understand them with this in-depth course. And practise with the exercises so that you can use them easily.

Extra Practice for the Tenses Course

Do you ever know exactly what tense you want to use, but you can't make it quickly enough when you're speaking? To speak really well, we need to train our mouths as well as our brains. This course has hundreds of practice exercises: PDFs, online exercises, flashcards with audio and audio exercises to help you form the tenses quickly, correctly and automatically.

Extra Practice for the Conditionals Course

Sometimes you know you need a third conditional, but by the time you've thought about the 'would' and the 'had' and the 'have' and the past participle, it's too late to say it. This course helps you be confident that your conditionals are correct by giving you lots and lots of practice to make them automatic.
