Anyone who is panicking, just try your best! Also remember unless you are dropping it next year that this is just a practice. However try do whatever you can to answer all the questions. There is multiple choice, so be careful. Many answers will be similar to try trick you! Do not spend too long on them, if you do not know it or it requires a long calculation skip it (Mark the page with a cross in the top corner) and make sure you come back to it at the end! Answer all multiple choice regardless of knowledge as there is a 25% chance you could get it right! If you have time at the end check your calculations first as this is where the main silly errors occur.
Good luck!
