To all those of you who are sitting the additional science examination, how are you preparing for that?

I'm reading my CGP guide as a recap over things I should know as well as completing past papers.

[usycool1]

I'm doing b3 (I did additional last year) but I'm doing past papers and I'm reading through my textbook

Good luck!

I have both B2 and B3 exams tomorrow, consecutively. We only just finished B3 about a week ago though so I'm just frantically reading through my notes, GCSE Bitesize and completing past papers.

Bitesize doesn't have B3 topics on, it sucks I use the textbook, even though the textbook we've been given is for foundation tier exams :/

[GrammarGirl]

ah I thought it didn't but then i thought am i just being thick. i'm quite nervous for this biology exam, b3 is very varied isn't it. and i'm retaking b2 as I got a B and my target grade is an A* so i've got a stressful day tomorrow

[letsbehonest]

I'm doing B2 and B3 tomorrow. Both at 9am - aaah!
Anyway, B2, I've only done a 2-3 hours revision, just read through notes and then done past papers.
B3 is taking the absolute piss. Doing the same for that but I've spent 2-3 days on it.

I'm doing B2, hoping to get a C. Going through the AQA revision guide, booklets my teacher gave me and the CGP work book and then in a bit I'm going to do some past papers

Doing B2 and B3 tomorrow these will be the death of me

B3 is omg so hard! I find it so difficult. particularly microbes and making ethanol and biogas and all that :/

Yeah, microbiology is the worst! I just really hope for an easy test but low grade boundaries (impossible, I know, but I can always dream)

What do the three of you find hard about it? Pray tell! We can help each other. It helps with our own revision, too.

[GrammarGirl]

praying for an easy paper tomorrow, pretty pretty please!!! a

[Nishat_1996]

Hopefully there is a good paper tomorrow, because apparently B3 In January was quite hard.
But i hope it's "alright" as if it's too easy, it means the Grade Boundaries are high.
Best of luck everyone, Hopefully you ALL do well! (:

Can you please tell me a couple of valid pros and cons of both kidney dialysis and kidney transplant? There are a few dodgy ones which I wan to avoid since they are only given in some past papers. Also, how to make ethanol-based fuels please

Kidney transplant:
Advantages:
No need to make regular trips to hospital.
No need to pay attention to diet.
Cheaper than dialysis in the long-run.

Disadvantages:
Need to take immunosuppressant drugs for the rest of your life.
Immunosuppressant drugs weaken the immune system, so the person who has had the transplant is susceptible to other diseases.
Risk of dying in surgery.
Hard to find a donor who is both willing and able to donate a kidney.

Pretty much the opposite can be said for dialysis (for both advantages and disadvantages)

Wow, thanks! I was just worrying because different people were telling me different things which weren't correct. But thanks for this list

[sheridanamber]

I'm resitting B2 tomorrow. I'm not particularly worried because I got a B last time and my target's an A, so the pressure's off a little bit. I'm reading through my notes, doing the quizzes on Bitesize and I'm going to attempt some past papers in a bit.
