I have just completed Verbs Modal - I'm not sure how I got through it, but I don't have a clue what I have learnt. Firstly what is a modal verb, and secondly what tense have I been using? Or was there a mixture of tenses in the two lessons. I have got myself so confused that for the moment I can't tell one tense from another! Can someone please try and unscramble my brain for me.
