**Higher level Biology 2012 Before/After**

Geographyhater

Thought i might get this thread going seeing its done for other subjects!

How are you guys set and what you doing this weekend for it!?

cocopopsxx

Thanks for this! Really needed it. I'm so scared about biology! I have a feeling there'll be a lot of plant biology and I suck at it any ideas what I should focus more on in regards to plant bio?

Schonie

Oh god...still have so much to look over...I'm looking over Photosynthesis, Respiration, Genetic engineering and Enzymes..

Stalin and rugby

Biology? lol that subject was designed to be crammed for the night before. Sexual reproduction of plants will come.

finality

I haven't looked at biology in about 3 weeks, but hopefully I knew it well enough 3 weeks ago that it'll all come back to me when I look over it this weekend. :L

reznov

Get ready for a roller coaster of a paper this year.

Well sorry to say plant biology is gna be coming up alot this year i have a good feeling about it!!
But on the good side it isnt that bad !! Know pollen grain and embryo sac formation ! And of course fertilisation! Then quickly go over everything else which will be shorter answer questions like germination!
Then go off do the exam paper on plants correcting off marking scheme youll be grand..

Ohh and know plant structure and cohesion and tension! And all the other aspects!

Ye im the exact same just goin over stuff right now that i havent looked at in an age!

Would i be safe leaving out studying DNA and genetics? Does it always come up as only one question on the paper and possibly short questions? Reallly hate it

FaoiSin

Hope the paper continues the trend of obscure questions being asked

Mayo_Boy

Im really fecked for this. Like is it actually possible to learn enough between now and tuesday to pass the exam or preferably get a D1 or possibly C3?

sean o r

Experiments will be enzyme based, well one of them anyway!

To be honest the obscure questions aren't all that obscure. They're actually simpler than some of the other questions..

As long as you know the course how they phrase the questions isn't a problem, just making sure you don't make stupid mistakes is the main thing.. it's what stops my A1 all too often..

Just go through papers with marking schemes. Learn off the answers. The same questions come up again and again.
Plant Biology, enzymes, genetics and ecology are going to come up.
Learn off the experiments. Really easy to do, just understand them. Questions on them are the same every year.

Our teacher never covered genetics because it is possible to leave it out, it just means you won't have a choice Although he did give extra classes to those who wanted to genetics...me.

I want to avoid genetics because I dont really understand it at all

FaoiSin

Genetics is a possible Section A question so I'd definitely do it.

cocopopsxx

Will human reproduction make an appearance this year?!

Namlub

I don't see them leaving it off two years in a row. I'm fine with all the reproductive system/germ layer stuff, it's just the hormones that get me.
I'd be so happy with a long plant reproduction question

Yes it didn't come up last year so it should this year. I haven't studied biology for a couple of weeks but I've unit 1,2, microbiology, human anatomy and experiments studied. Going to take 2-3 hours now to go over it:D

Britney_Spears

I hate ecology so much I'm good at everything else but what do I need to know for ecolgy in short questions I will be avoiding it in section c

Definitions basically.

You could leave it out if you knew everything else well enough. However, even if you leave out the more complicated stuff, you should still know the basics (definitions, structure) as they're not difficult short questions, and they could be asked as part of the experiment questions. Don't skip the experiment on DNA either, the questions usually just go through all the steps which aren't too complicated to go over!

leaveiton

Bit scared for this as I haven't looked over any of Unit 3 or DNA yet but I think I should be okay overall. My teacher's given about a billion tests throughout the year though so I've learned everything at one point. There are only a couple of Unit 3 chapters that I'm not really comfortable with but I'll be able to study them before the exam. I just hope it goes well, I really need the A1 in this.

Emz93

do you think i'd be safe covering everything except Sexual Reproduction of flowering plants? Going for an A1 so would be able to answer any other questions hopefully if given a choice! I was out for the two days my teacher did it in so i'm fairly lost!

People going for an A1 shouldn't be leaving anything out, to be honest...

ChemHickey

I'd be disagreeing about leaving out genetics etc.

One year two short questions arose on genetics and it caught the schools who's teachers decided to skim over it. I'd learn both genetics and ecology as they are the main sections in the book, and, they are interesting ones!

Zomg Okay

Ecology, Food and Genetic Terms and Crosses have come up every year since 2005. They better keep that up or I will personally hunt down and kill everybody in the SEC. :rolleyes:

True..i'll learn as much as possible then! It's all so abstract

DNA, Ecology, Photosynthesis, Respiration and Digestion are the key things I'd know for this year. You can almost guarantee a question on at least 4 of them either in short questions or long questions. Excretion came up last year so I reckon there won't be a long question on it this year. (don't hold me to that though if one does turn up :pac:) Although in saying that you should still know the general gist of it in case it turns up in the short questions

Also, know your experiments well. Not only are they worth 60 marks but the info you learn from them will definitely help you in other parts of the test. I'd say we can also expect an experiment similar to last year's q7, not an experiment we've actually done but one testing the theory behind them.

biohaiid

Been all day so far trying to do genetic crosses etc .. still cant. fail.

Spattersonox

If you want an A1, there is not such thing as ''leaving things out''
I'll be doing all the expt questions and an extra long question.. just incase

biohaiid

Do we need to know the measures for chemicals in the experiments?

Joey.

Definately not?
So what, we'd just say like 'Add yeast' instead of 'Add 2g yeast' ?

Maybe in the IAA experiment, but otherwise there's no need for them. So yeah pretty much

smithy77

Did 2.5 hours of biology there went over Unit 1 & 2 and did a few exam questions aswell:) .. Going to do the experiments and human anatomy tomorrow and hope the rest sticks to my brain:p

Helloxoxo

Not so sure leaving genetics out is a good idea? There could be 2 longs questions on it like our mock, and it's very easy to get marks in

reznov

Genetics is repetitive and the questions they ask are limited. Not worth leaving it out whatsoever.

Bit random but if your doing ag science aswell genetics is important to learn for that and biology.

Worried101

HELP!

I really want a C1\B3 in biology, but would like advice for what Experiments to focus on! As they are worth 20% of the toaltal grade! In my mocks i would had done better but didnt really know the exps. in depth.
I've been focusing on effect of co2 on photsynthesis and ph exps., any other suggestions regarding exps. or exams?!?!?

Does anyone think genetics will come up on shorts, as i dont know that chapter well at all, thanks!

Zomg Okay

It's come up in shorts and longs. Sometimes both.

I'm really hoping for an A1, I've left nothing out.....so fingers crossed
and I was just wondering should i do an extra question from section C or should i just do four really really well? ??

There's usually plenty of time left over in biology, so if you had the time to do an extra question I definitely would. It won't cost you anything and even if you're confident on the 4 you've done, you never know if you've misread a question etc and could do with a backup.

Cruel Sun

AWWW God, I'm not the best at Biology so I literally predicted the **** out of the course. I was fairly confident that my predictions would get be the B I want......but after the last few days.

personally id do four really well and cram ever bit of information into it i knew...make sure that what your including is correct do...a wrong answer cancels out a right answer...dam negative marking!

My favourite chapters! Don't forget reproduction too!

ye, experiments should be a handy 60 marks hopefully but I was out doing the leaf yeast and dissection so I'm not as good with them as others.

My sister gave me her dissecting kit from college so I plan on doing dissections over the summer

In my mocks I did them all except 1.

If you do want to do an extra question, I recommend doing an extra part in the 14 or 15 part. That's what I plan on doing. Do all 3 ; a/b/c

PTheArtist

I'd say the IAA experiment and one of the enzyme experiments will show up this year.

ya fair point..thats not a bad idea..incase ya make a balls of one of them!

ei.sderob

Ugh, really don't want the IAA to come! It's the most complicated method in my opinion and describing the serial dilution is just tedious.
