I know most content but I keep getting questions wrong what should I do?

WIth Biology it is very important that you use specific words and many marks schemes require you to say a specific word such as monomer/ hydrolysis/ allele in order to get the mark. I found that when I would lose marks in a test, I was describing the key words without actually stating them. One thing that helped me overcome this in a short amount of time, was doing the same past paper questions over and over again before a test so that when it came to an actual end of topic test, I would get full marks on recall questions. In preparation for Year 13, I bought an A5 notebook where I wrote my neat notes. Writing my notes in there meant I had limited space to write my notes (unlike the previous year where I had a large ringbinder for notes) therefore, only wrote the most important points which made revision easier.
