WJEC Biology Help

Hello. I was wondering if anyone else takes AS Biology with WJEC. I find the content enjoyable and interesting, I have got my head around most of the concepts.

However I am struggling to answer the exam questions well. I usually put things down that are correct but either aren't on the mark scheme or I have not used the correct phrasing to gain the marks. I find the mark schemes for BY1 and BY2 so tedious and picky and it's difficult to see what phrasing they want from the original question. Also I have found the ten markers a nightmare, and I usually score 4/10 or 5/10 where I should be doing better. I just can't find a good strategy to attack those questions so I have stuck with bullet points. I find that the topic they choose is so broad e.g. "describe the functions and structure of lipids and carbohydrates in organisms" yet they only have about 14 acceptable points on the mark schemes.

I have been fumbling around the C/B borderline in tests and I would really like to get an A. Has anyone got any advice on how to approach the papers and boost my grade, especially the 10 marker?
