The End of unit test for this achievement standard is next wednesday. Here is a practice paper for you to try and find out those aspects you need help with. Complete the paper as homework for Monday. I’ll put a tutorial answer on the blog on Monday for you to check your answers.
There will be a tutorial in Lab 52 tomorrow morning beginning at 7.30 when we will do this paper and you can sort out any issues then. I realise it is an early start but you will get your homework done and not need to slave over science during the weekend. It also signals to me that you are committed to getting a result in this externally assessed achievement standard. Good luck
