OCR AS Biology Exam - How did you find it?

interphase: i wrote about dna replication and gaining energy because mitosis is an active process.

Just looked it up.

Should be:
First growth phase when the proteinsfrom which cell orgalles are synthesised are produced.
Synthesis hase, when DNA is replicated.
Second gowth phase, when organelles grow and divide and energy stores are increased.

I also wrote something like cromatin replicate to make chromosome, think that might count.

Hi! I did all 3 this morning. Foundation was good, HHD too vague, too much graph interpretation and the long answer question on T lymphocytes was horrific and transport was mostly alright.

At my school we had to start the exams in semi darkness as some prat had cut the electricity cable to the school. I had the added problem that my reading glasses have lenses which are yellow (to stop me getting migraines from the flourescent light) and when there is no light it makes it a bit difficult to see. The lights went on and off a couple of times before finally staying on about 10 minutes in to HHD!!

Hope everyone elses went ok. :biggrin:

did they give u extra time because the lights went off?

No-our teachers are so evil! They said they looked into whether to postpone until the power was back on, but since it was a "nice sunny morning" we would do the exam with the light from the windows.

The windows are about 30cm x 15cm and right up at the top of the gym walls. Not exactly much light!!! :biggrin:

I really wish I re-took Foundation, everyone keeps telling me that it was really easy.

I also found in HH&D it was difficult to get in 'biological' knowledge on some of the questions. And I think some of the graphs were diffcult to describe - there were so many increases and decreases.

I don't know what the weathers like elsewhere in the country - but it's like 29 degrees here, I really couldn't wait to get out the exam hall.

1 lousy mark of a B :frown:

- I was totally unprepaired for the exam though, so I think I was lucky to get what I did.

it wouldnt be like that because each of the different exams is worth a different percentage overall.

transport = mark you think you got/45 x 0.2 x 100

HHD = mark you think you got/60 x 0.3 x 100

foundation= mark you think you got/60 x 0.3 x 100

and then add them all up and thats the percentage you got out of 80%. it depends on how your coursework or practical went for that extra 20%

Questions I can remember for HH&D (not word for word, not in order or even probably accurate):

- 3 components of a diet that provide energy

- Tick sheet of Essential Amino Acids/ properties ect

- Long term effects of starvation other than growth

- Two disease described in paragraph

- How CO & NO increase clots and atherosclerosis

- Clotting and CHD

- Percentage question on graph

- describing graph of TV & max capacity

- The ambiguous question on mucus/decreased surface area

- 3 ways HIV transmitted (other than sexual contact)

- Lots of questions on describing graphs (AIDS)

- How health statistics are helpful

- 'Fill the gap' Exercise on Immunity

- Essay question on T-cells

All I can remember. If anyone wants the Transport questions up that I can remember, just ask.

The two questions on Zimbabwe and the UK i swear I end up putting the same answer for both! Those questions were annoying. And for the stuff about homosexual men, why is it on the increase? Gosh I was such an idiot I was frantically searching for something to say- I put about increased sexual freedom and onset of immunity to drugs whcih I think is completely wrong, I also wrote about drug development and AIDS awareness for other questions which I dont think is what they were looking for.

For Foundation, the first page, what energy is needed for chemical reactions to take place and what is the DNA strand thingy about?

ANd for 3 ways in which AIDS is contracted I could only remember 2 :-/
