Capital letters can be a real problem if you are not sure about how to use them. You all know that the first word in a sentence is written with a capital letter.
The best way to get to know the English language is through practise. If you enjoy reading, then make sure you read a story, poem or even news article every day. If you like to write, then spend 10 minutes each day writing something - even if it's a little note to yourself. If you are unsure whether a word needs a capital or not, then check it in the dictionary. Some words sometimes take a capital letter and sometimes don't - such as the word north - it's important to know the difference.
In this 11-plus quiz you are going to learn about a few more uses of capital letters.
