helpful information regarding as level biology - new specpersonally, i thought the exam went decent.
Did any of you guys know about a second set of specimen papers? I did them and most of the questions were based off of paper 1 from set 2.
I guess the next best thing to do is to
concentrate on paper 2 on tuesday 7th. i have compiled a list of topics that were not featured on paper 1 (26th may) and so may come up in paper 2:- carbohydrates
- more on dna and rna / protein synthesis
- eukaryotic vs prokaryotic cells (comparison of organelles)
- size and surface area
- gas exchange (lungs, fish, insects)
- digestion and absorption (there was 1 question in paper 1 but mostly regarded lipids/triglycerides/hydrolysation)
- haemaglobin
- circulatory system / the heart
- plants: Xylem / pholem
- biodiversity / standard deviation
- taxonomy / natural selection / variation (alleles)
- meiosis
- mutations
as far as biochemistry tests go, lipids/emulsion test will not come up and it is doubtful that the benedicts/sugar test will come up. Revise: Biruret/proteins and iodine/starch tests.here is a list of what is less likely to come up as was featured on paper 1:- lipids and proteins
- enzyme action including factors affecting (inhibitors)
- dna/rna
- atp
- inorganic ions
- mitosis
- cell membrane
- diffusion / osmosis / active transport
- the immune system and immunity/vaccines
- antibodies in medicine (elisa)
- hiv/viruses
- there was 1 questions regarding mutations, but suggest revising it anyway.
I am going to revise the hell out of these topics ^
you can find the specimen set 2 papers + mark scheme on this thread,

I also suggest watching 'mr pollock biology' youtube channel!
Good luck guys!
