Started my annotations for the pre-release already

Based on my annotations, I assume the following may pop up:
- Genes, DNA, PCR, translation, transcription (unit 4) and transcription factors (unit 5)
- Global warming (there's mentions of carbon dioxide here and there)
- Structure of bacteria, cell walls of bacteria - Mycoplasma are a genus of bacteria that lack cell walls
- Photosynthesis, GPP, NPP, biomass
- Stem Cells, ethics
- Biological molecules (maybe)
- Drug development
- Brain matter (very vague though)
- Enzyme structure and proteins

Yep, I've predicted all that too :smile:

Also cancer (unit 2), human genome project, genetic engineering, switching on and off genes, master genes and cloning etc

I have a question about getting the A*! I got 265 UMS at AS (A). I know I need 90% in both Unit 4 and 5, but what overall UMS do I need to get an A*? Like I'm sure you have to get a minimum of ___ UMS and then A* in Unit 4 and 5 for the A*. Any help would be appreciated

minimum ums of 270/300 from units 4,5 and 6, totalling a minimum of 480 across as and a2. i.e 108/120 in unit 4, 108/120 in unit 5 and 54/60 in unit 6.

Okay thanks!
It also says that when depolarisation occurs, localised currents are generated in the membrane, so what does it mean and what are they for ?

If I got 258 ums at AS what would I need at A2 to get an A overall?
also what would I need if I didn't do very well in the coursework?

An overall a grade is 480 ums. So I'm sure you can work out what ums is needed this year. If you know your coursework grade you/I can work out what you need to get an a grade.

So I would need 222 ums this year overall? I don't know what I got for my coursework, just want to be prepared for the worst

so say if I got 30 ums in my coursework, I would need 96 in both my exams - that seems weird because that's only just an A?

Okay, but if I got less than 54 in unit 6 won't my AS UMS make up for the lost UMS in my coursework? Or do you have to get an A* in the coursework as well? :/

You have to average 90% across all three A2 units. Therefore technically no, you don't need an A* in the coursework if you did really well in the other two units.

AS UMS does not contribute to the A*. You need 90% average across a2 units and an a grade overall. You could get 120/120 in unit 4, 120/120 in unit 5 and only need 30 ums in the coursework and still get an A*.

Does anyone have the link for the pre-release? Not sure if I've printed the right one. The one I printed is about aging and disease, free radicals, parkinsons disease.

If your mock is the 2015 paper then you don't have to look at it :biggrin:

I don't know for sure but it would make sense, however surely they should know they'd be released to the public? Bit too late for that :redface:

Not sure tbh. My school never did stringently controlled exam prep, rather working through exams as pairs. Do the paper if you want to; at this point it's all about you not the school.

Q) In unit 5 to do with spirometers do we need to know about Vital Capacity, Residual Volume, Inspiratory reserve volume etc. I think it's a bit advanced so I want to skip it but is anyone else revising it or even heard of it.
