When you visit the MyMaths website you will see a screen like this:

At the top it has LOGIN and PASSWORD fields. Enter "stratfordhigh" as the login and "square" as the password.

When you then click on the "Go" button you will see a screen like this:

At the bottom left in the pink strip you need to fill in your own personal login and password. Your login is a number and your password is a word. Do not get them the wrong way round. When you have entered the details press the "View" button

When you have done your homework, you must click on the "MARKIT" button on each page (there are generally 2 question pages).
