Why do I keep losing marks on 6 markers?

My best tips for you are: 1.) make sure you have 6 DIFFERENT points; a good way to keep each point clear is to write in bullet points instead of paragraphs (you can always write more than 6 if you think they're all viable) 2.) Try not to repeat points just by wording them differently .3.) 6 markers usually demonstrate your understanding of a certain system or phenomena e.g standing waves, so try and work chronologically through the system in order to get each point. 4.) Study mark schemes! These will tell you exactly what examiners are looking for.
