Title: 80 Hours Until Biology: The Final Gameplan
Post by: naomisirmai on October 16, 2016, 04:34:00 pm
Practice papers

Smash out some last few practice papers for that extra confidence boost, and to work out exactly how you’ll manage your time in the exam. With some luck you can crush the MCQs in the first 20-or-so minutes, leaving yourself more time for those tricky 7 and 8-markers.

Make sure you complete all questions every time. You’ll have to do so in about 80 hours, so there’s no use taking the easy route now. The more questions you answer, the more confident and capable you’ll be on the day. A sure-fire mark-booster.

Some final tips for those higher-mark questions:

-   Dot-point out your structure and examples beforehand… Try to work out what the markers are looking for, and use that to decide how you will answer the question in the most effective way.
-   Underline/flag key ideas… If the question is asking you to talk about three different scientists, structure your answer by scientist, and start a new line for each. Make your answer legible and clear.
-   Give enough examples… For an 8-mark question, give three examples that are properly explained, with all key terms defined.
-   Answer explicitly, using the words of the question… make it EASY for the marker to give you marks. They’re overworked teachers who are often just looking for things to tick. Make sure that they know that you’ve answered the question correctly and thoroughly.

Memorising

Now’s the time to cement a shit-tonne of information into your tiny head (am I allowed to say shit? whatever.). This seems like a massive task, but if you break it down into manageable bits, it will be much much easier.

To help you structure your study, here are some things you should have memorised:

-   Definitions (of everything. Begin every higher-mark question by defining key terms)
-   Processes (ultrafiltration/reabsorption/secretion in the kidney, xylem/phloem in plants, the immune response)
-   Lists (the steps of evolution by natural selection, Koch’s postulates)
-   Experiments (Mendel, Morgan, Beadle and Tatum, Pasteur etc.)

Consider the fact that you’ve utilised much of this information before – half-yearlies and trials, plus in all those practice papers. For some dot-points, your memory might just need a quick booster before it all comes flooding back. For others, it might all seem brand new. Try not to freak out, just give yourself the time that you need…

I read things out loud to myself, tried to explain concepts to my cat (pictured below), and recorded myself reading content and listened to it. You could try Jake’s technique of writing out everything you don’t know in a sweary ‘summary sheet’, but make sure not to intimidate yourself – just include the absolute essentials.

my cat Rory (yes really)

Spend some extra time on your option

Unless your school is super edgy and does the content in a different order, your option will likely be your weakest area. You probably learnt it at the same time as studying for trials - trying to fit all your other subjects into your head - and either wrote your own notes without really thinking about them, or tried to memorise someone else’s notes without actually ‘getting it’ (guilty...). Compensate for this by giving yourself another opportunity to truly understand the key ideas in yours. What are the key ideas threaded throughout the syllabus? How do they link to each-other, and how do they link to the core Bio syllabus? Now’s the time for sketching out mind-maps and talking to yourself.

Summarise summarise summarise

There’s no use memorising essay-style answers to dot-points. That’s just not going to be useful come exam time. Try to synthesise key content into dot-points, diagrams, and even just key words. There are certain things that you’ll DEFINITELY have to know like the back of your hand. These things are scientists and people. I made myself some palm cards with literally JUST the key content on them.

To help you out a little on your quest for godlike biology knowledge:

Eat some celery

If my memory of being a 6-year-old doesn’t fail me, you are what you eat and it also takes one to know one. Thus, in order to truly understand the nature of xylem and phloem, water and glucose transport, respiration, and cell-structure, you must imbibe of the plant itself. This is the most important step.

Take care xx

This was really helpful! Thanks Naomi :) also, would you recommend condensing all your notes to a minimum amount of pages possible, as a primary study method?

And would you have any suggestions for the night before the exam? e.g. lightly look over notes or do the 2015 paper?

I'm so glad you found it helpful!
I definitely recommend condensing your notes. Have the main ideas on the page and the detail in your head, ready to be unleashed come exam time!

As for the night before, I would highly recommend chilling as much as possible. You want to clear your mind so that you don't go into the exam with any presumptions about what might be asked, because that can lead to confusion and anxiety when there's an unexpected question. I would have a scan through my notes before bed, then try to have a good night's sleep. No practice papers!
I plan to make another post about this though, so stay tuned... :D

Hello Naomi, I have a double the day before the biology exam, both requiring quite extensive memorising and energy. I've already memorised everything for biology and did a few past papers, but that was a few days before hsc started and I know that the information I've remembered word for word I've started to forget... what would you suggest i do the day before biology?? should i try and go over and memorise stuff that I've forgot, or do past papers? my exam the day before finishes at 17:00... I'm not sure what to do. thank you so much for your article :)

Argh that's unfortunate. I reckon you have already set yourself up really well by doing some serious memorising before exams started, so well done for that!
The evening before, I'd say DO NOT do any practice papers. I think, because Bio is so content-heavy, re-memorising high-yield would be the most useful thing for you.
Good luck!

Thank you, Naomi!! :D
I was just starting to freak out over how much content there was in biology and how little I knew but this has calmed me greatly.

And, ew, celery. hahaha!!

What other things would you put in a little table you made?

Thank you again :)

Hey so in the table I'd just have a one-line summary of what they did, or even just one keyword to jog my memory!

Lamarck proposed the theory of 'Inheritance of Acquired Characteristics'... Basically he believed that if a parent acquired a characteristic over the course of their life, then they'd pass it on to their children genetically (not true! it has to be a mutation in the gametes to be passed on!). The example he used for this was that he saw giraffes stretching their neck to reach leaves high up on trees. He thought that if parents stretched their necks, the baby giraffes would inherit longer necks.

Eldridge and Gould proposed the theory of 'Punctuated Equilibrium' - that evolution is not just a linear process (always occurring at the same rate), but that there are periods of fast evolution followed by not much change at all, prompted by environmental change. Makes a lot of sense if you think about it! Especially given that evolution by natural selection is driven by environmental change.

Great article, helped me calm down about biology.
I've scanned over the syllabus and i feel as though I have gaps in my knowledge, like, I know a few points but its never in detail.
I'm worried about the amount of time left till the bio exam.
would you recommend me doing past papers first or recaping content?
thank you so much guys  :D

My friends and I just had a discussion about your comment!! Very interesting, thank you!
Although Lamarck didn't have the exact right idea about it, there is a lot of research being done about how things like stress can be passed down genetically.

I reckon spend a day doing as many past papers as you can - they'll help you work out what you don't know.
After that point, knuckle down on study. Maybe a past paper here or there, but really focus on memorising and getting that detail in.

OMG did you seriously just ask this? I'm not saying to take a leaf out of jake's book and put it in the title (;) lol) but you can definitely be a bit more relaxed while typing, truly express your feelings :D

But my actual purpose for this comment is to say that this is an awesome guide!! Thanks so much for doing this and do dogs hold the same amount of attention when you talk to them as cats? Lmao
I fortunately do like celery so I'm going to stain myself and identify my companion cells and sieve tubes ;)

Soz if I was too savage, but I get sassy when I'm tired and I just had a 3 hr senior science paper today 💤💤

Thank you! :D

Just thought I'd pipe up again, (better late than never!) and just simply state that nowhere in the syllabus does it say their names. The dot point is does relate to is one that you most like did Charles Darwin for "a scientists theory of evolution blah blah blah"

There are more things like this throughout the syllabus (eg 9.1 Skills- practising male and female scientist, destructive/non destructive testing etc)
Just do yourself a favour and just once, look through the whole syllabus and note the wording.
(Including macfarlane burnett, so easy to forget as he is in the first column)

Good luck everyone!!!!

Hey,

I keep getting confused, but what exactly is the difference between a dominant and a recessive gene? How would I know if a condition is recessive or dominant from a pedigree?

Thank you :)

Hey,

I keep getting confused, but what exactly is the difference between a dominant and a recessive gene? How would I know if a condition is recessive or dominant from a pedigree?

Thank you :)

So basically a dominant trait will be what comes out in the phenotype (i.e. in Mendels pea experient tall was a dominant trait to any genotypes that had a tall allele would result in the plant coming out as tall; dominant is always expressed as a capital letter). Recessive is basically the opposite, it's kind of the trait that one see's unless there are two of them that make up the genotype which relates back to Mendel's ratios of 3:1 in phenotype.

The second part to your question i only really figured out after sitting my trial exam because i got it wrong lol but the easiest way to figure out if a trait is dominant or not is to draw pedigrees. I like the look for a specific branch where two parents have the same phenotype (both have or both dont have the trait) and then observe their children. If say both parents do not have the trait but one or more of their children do then that means that the gene must be dominant. You can check this by asking yourself if the gene is recessive will both parents who are homozygoous recessive produce anything other than homozygous recessive offspring which is no

I am really bad at explaining but I hope this helps!!

At this point there's no point panicking.
Your focus needs to be memorising, and you need to memorise hard. Whatever techniques you use, use them. You won't be able to nail the full 80 pages of notes, but with some luck you will be able to get the essentials done.
If you don't understand, ask questions on the forum.
Good luck!

100% you can pull it right out of there. Memorise the shit out of everything. Bio is like 70% memorising, 30% application, so you could smash the memorising then scrape marks in the longer-marked questions.
