Year 7 Block C Homework Booklet
Revision Questions!
Just after the half-term holiday, in Block C Assessment Week,
you will be sitting a short test on some of the topics you have
studied this year.
The question in this homework booklet will give you an idea of
the style of the test, and some of the topics which you will be
tested on.
Don’t forget to ask your class teacher if you want to know any
more about the test!
As always, you should try to complete all the questions in
this booklet.
Don’t worry if the questions at the end seem a little harder;
they’re supposed to be! Just do your best and fill in an answer,
even if it’s a guess, for every question.
You CAN use your book to help you and you CAN ask your
teacher if you get stuck.
