The exam for Woodwork or Metalwork are both worth 30% of your final grade with the other 70% being your final practical model and your logbook.
Speak to your teacher if you want to arrange coming in for some extra time to ensure that you get the model done and assembled.
The exam will focus for both courses on material properties, tools for marking out, cutting and shaping, machines - safety features and how to use them as well as being able to name the part, describing processes for marking out or cutting particular parts, reading drawings, and PPE/Health and Safety. There are notes for all of this on Teams to help you - and you can use past papers to practice the style of questions that might come up.
Woodwork is also on Achieve - ask you teacher for your log in if you don't have it yet.
