don't we all... I always make silly errors..

It's horrible coming out of an exam having thought you did better than you actually did (after having compared the answers with everyone) ah well, fingers crossed I didn't completely fail! How do you feel it went for you?

That's good! Yeah most people are saying that

I said that the graph fluctuated largely 6 times for the first question ;p Would I get the mark?
Oh, and what would I need to get to get an A* if I got:
31/45 for Unit 1 (100 UMS)
34/40 ISA
32/45 Unit 3

What UMS did you get for unit 2?

Well all I really meant was what would I need to get in Unit 2 to get an A*?
edit: Think I got 32 for Unit 2. Would that be enough ?

quote me if you wanna see the UNOFFICAL mark scheme

im serious..

[Alinator]

1a) i) There are six ‘peaks’ between 7.5 and 18 minutes. (1)
ii) 2.5 minutes (1)
b) Supply oxygen (1), glucose (1), remove carbon dioxide (1) , lactic acid (1), to limit anaerobic respiration (1), to create energy for exercise (1). (Max 4)
2 a) To keep out oxygen (1) which would result in aerobic respiration, whereas biogas is produced best in anaerobic conditions (1).
ii) Carbon dioxide (1)
b) 0.62 (2)
ii) Adding fish fat, increases yield of biogas/methane (1). Better quality biogas, as higher proportion of methane (1).
c) It would be too expensive to buy the fish fat as he can’t fish himself 100km from the coast. Therefore, better quality biogas not an economic advantage (1).
3 a) Aerobic (1) respiration (1)
ii) So that all Fusarium has equal access to the minerals, resulting in even growth (1). Even control of temperature around the fermentor (1). (Max 1)
b) Would get tangled around paddles (1).
c) Chicken has more protein for making new muscle cells (1).
ii) Less fat/cholesterol, so less risk of circulatory problems (1). More dietary fibre, reduces risk of colon cancer (1).
4a) Higher concentration in plant roots than in soil, so absorption against the concentration gradient (1). Diffusion is along the concentration gradient (1).
ii) Active transport (1).
b) i) Larger surface area (1)
ii) Mitochondria site of respiration in a cell (1), so more mitochondria results in more respiration, increasing rate of active transport (1).
iii) Starch broken down to glucose when needed for respiration (1).
5 a) Urea, mineral ions (2)
b) All reabsorbed (1), first by diffusion (1), and the by active transport (1)
c) Kidney wants to reduce glucose levels so that they are healthy (1), so selective reabsorption means than not all glucose is reabsorbed (1).

6a) Increasing DAS concentration, decreases yield of alcohol (1), numerical evidence (1). DAS only results in less maltose being used (1), glucose and sucrose not affected (1).
b) Maltose too large, so insoluble (1)
c) Enzyme is a carbohydrase (1) which digests maltose into two molecules of glucose which can be used for respiration (1). DAS stops production of enzyme so maltose cannot be digested and used for respiration (1).
d) DAS reduces yield of alcohol, reducing profit (1). DAS means that most of the malt extract is not used, so killing DAS means manufacturer has to spend less on malt extract (1).

I think the exams went OK...
They weren't super easy but hopefully I did all right.

I noticed the question on the advantages of an increased heart rate for exercise was repeated on a few practice papers. :P

How did it go?

[Revision-]

Damn think i lost about 10 marks =[

The thing that pissed me most was I put anaerobic fermentation for Fusarium ;[ (I know right)

will 33 be 78 UMS?

Nope I'm pretty sure that's going to be in the 90s...

My friend put 'aerobic fermentation'

[amber206]

I completley just failed that B2...
What's an A for B2 anyone? :/

[Will-2609]

For the first part of the mycoprotein question I said the chicken contains more energy, would I get a mark for this?

Well if you got 100 UMS In unit 1 and 85 in the isa (that's what I worked out 34/40 to be) and 87 or 89 in the unit 3 (that's a bit of a guess, it may even be in the nineties!) then I'd imagine you need 88 or 86 to get an a*? Which will be probably be 32 yeah I reckon you've got quite a comfortable a* there personally! But it all depends on the grade boundaries :/

Sorry if I've confused you! Hahaha :')

[AngryBirds4]

I thought is was an alright exam - Could've been a lot worse though!

I thought B3 wasn't too bad, it was easier than B2 at any rate...

[anaelena48]

what would be the unofficial mark squeme for unit 3H along with the questions?

why would you need the questions if you took the exam? besides, if you did take the exam - you vould vaguely remember the questions by looking at the answers..

[ryazd]

do you reckon 37/45 would be A*? also for 5(c)(i) if you put there is a higher energy intake, would you still get the mark ?
