IMPORTANT to use the Pre-Assessments as practice and a pre-run for assessment. Checking and running through the answers should build your confidence. You will realise anything you need to brush up on but also how to problem solve through processes and steps through calculations.

Further revision:
Use the notes, presentations, video tutorials, exercises, worksheets - try to answer questions using the material provided, then, and only then, CHECK answers, locate where there might be issues, try again, then look at the answers to assist with learning.
​
Always worth trying and keep trying to learn prior to exercises and worksheets, then learn some more, keep trying, then CHECK against answers.

Please do NOT use until attempted the Pre-Assessment and used notes to learn more. It only cheats yourself and can cause issues.

PRE-ASSESS ONE ... This one first

PRE-ASSESS FINAL- PLEASE DO NOT CHEAT YOURSELF - attempt first, use notes and video tutorials before looking at the answers to check.
