For the first term exam you must revise and study:
Unit 1 - The Earth in the Universe
Unit 2 - The Water Planet.
It's important to read carefully through the units and it's a good idea to underline the important parts (with a pencil). Try to think about what we have insisted on and repeated in the class.
It's also a good idea to read through the activities we he have done, the exam questions will be similar!
