Introduction

Welcome to the subject of Biology. From DNA to the evolution of species to the interaction of all living things on the planet, Biology explores the wonder of life, and it unpacks the remarkable functioning of organisms. I hope this guide gives you some tips and tricks to navigate this content rich course.

How to prepare for your IAs

Your IA for Biology makes up 50% of your final grade. You will have 3 IAs throughout
the year, a Data Test (10%), a Student Experiment (20%) and a Research Investigation (20%). Achieving your best in the IAs will put less pressure on you during the exam period.


Data Test Preparation

The Data Test focuses on the three of the assessment criteria; apply understanding, analyse evidence and interpret evidence. It is a test designed to assess your ability to complete calculations and identify and draw conclusions about biological data sets. To prepare for this test, completing as many review questions that use datasets from graphs or tables or require you to use formulae to provide a calculated response is recommended. Practise, practice, practise is the best advice.


Student Experiment and Research Investigation

Your teacher will be your best source of guidance for these tasks. Two pieces of
advice I would give you to help you achieve your best with these IAs are:

  • Sufficient and relevant data

    For both tasks you will need sufficient and relevant data. This must be enough to be able to answer your research question and support your findings. For the Student experiment, ensure that you have a large sample size to improve reliability and validity of your data. Things to consider could be number of sample sites/quadrats, variations in independent variable (e.g., 5 different pH values), number of trials per variable. For the Research Investigation, ensure the datasets you have found consider both variables in your research question. Sometimes you will find datasets that combine both but other research questions you may need to find datasets for each and draw conclusions to show how the two variables link. Remember more data in this task is not necessarily better; only include statistics and data that are relevant and help you answer your research question and respond to the claim. 

  • Submit a complete draft

    Drafting is an opportunity for you to make sure you have included all the aspects that are required in the task. It is important that you draft you submit for feedback is as complete as possible. Have the mind-set that you are submitting your report for final marking, The feedback you get back from a
    complete draft will be far more useful than feedback on a draft where large sections are missing. Take the time to speak with your teacher if you are unsure of any feedback comments provided in the draft.

How to revise for exams

Use the Unit Overview

Your biology teacher will have a unit overview that you will be able to access to ensure that you are covering the concepts required by QCAA. Make yourself a checklist or mind map and place it somewhere visible so you can list or check off the content as it is covered in class or as you revise it. Success is all about making sure you are confident across all the content you have covered.

Organise your notes

Notes are the best place to start revising. Research suggests that the act of writing
notes is one of the fundamental ways to retain and consolidate knowledge. Using your checklist of what you should know, make sure you have a set of notes for each of the topics. Make use of the resources provided in class to develop your notes: class PowerPoints, the Biology textbook, suggested activities from your teacher.

This will help you focus on what is an appropriate depth of knowledge and avoid wasting time scouring the Internet. Organise and annotate your notes in a way that makes them easy to refer back to when it’s time to revise. It is important you find what works for you. Organisational ideas include:

  • Headings & subheadings

  • Use of colour/highlighting

  • Detailed/annotated diagrams

  • Bolding and underlining

  • Concise explanations

  • Flowcharts

Review your notes

As you are developing your notes, you will need to periodically review them.
Throughout the year, go back and review the notes you have taken. This may be
reading over them, writing them in summary or having someone ask you questions.
Don’t forget that video resources and animations are often a good way to visualise
concepts. Use the checklist or mind map to keep track of the content you have
reviewed.

Do questions to increase confidence

The difficult part with revision is knowing what you should be focusing on. For the
external exam, you are revising content in case it is on the exam. You have two units
of content to revise so you need a strategy to work with your strengths and weaknesses. You can use your checklist or mind map to identify the content you are confident with and also those areas that you need to work on. Actively seek out questions that will test you on the concepts you need to work on. Practice questions can be found by:

  • Reviewing class activities, worksheets or practice tests

  • Accessing the quizzes section on Studyclix

  • Choosing questions from your Biology textbook

  • Asking your teacher for extra questions on a particular topic (teachers
    always have heaps handy)

Once you feel confident on a particular concept, move on to the next one. Don’t
forget to do a couple of questions on those areas you are confident as it will help
keep you motivated when you achieve success.


Create a study timetable

In the lead up to the external exam, it would be a good idea to set up a study timetable for all of your subjects. Use a simple calendar template for the weeks leading up to the exam and note when each of your exams are timetabled. Working backwards from your last exam, allocate days and times to study for your exams. You could even allocate specific topics to be covered for each subject.

Reviewing the mock exam

At the end of Unit 4, your school will have you sit a mock exam. This is a really useful
tool to see where you are at in Biology. Approach the mock just like you would the actual external exam. Set yourself a study timetable and review those areas that you are less confident in. When you get your mock exam results back there are a few things you should check:

  • Which questions did you smash?

    No matter how many or how few you completed successfully, acknowledge your strengths. Mark these on your checklist or mind map. These are the topics you have mastered.

  • Which questions did you miss?

    Remember this is a mock exam so don’t be disheartened. Now you know what you don’t know. Mark these in a different way on your checklist or mind map. This has helped you identify the areas in the content where you need to fill in the gaps in your knowledge. It has given you a starting point for the final exam revision. 

  • Are there any styles of questions that you are better at?

    You will find that there are some styles of questions you are better at than others, multiple choice, interpreting data, interpreting diagrams. Go through and identify your strengths and weaknesses considering the style of questions and try and
    choose questions to practise to help improve success across all styles of questions.

Study and practise

To achieve your best external exam, you need to review your content and practise
exam-style questions. There are many ways to test your knowledge and it is
important that you find what works for you. Here are a few suggestions.

  • Practice exams

    Completing practice exams will always be helpful. Set yourself a timer and complete the questions under ‘exam conditions’.

  • Develop your own study resources

    Flashcards, summary notes, audio of your notes; there is an endless array of things you can do to help you study

  • Study groups

    I am a big believer in the value of a study buddy. Set a time to get together with a group of friends to review questions, share study resources, test each other and discuss how to approach the exam. Hearing content explained by your peers can be invaluable.

Exam Day

Perusal Time

  • Use the perusal time to get a feel for what topics are covered in the short answer and the marks allocated.

  • Read and analyse any stimulus or data. Consider what are the variables and how they are interesting.

  • Plan your approach during perusal. Will you complete the exam from page 1 to the end or will you complete the questions you feel confident with first.

Completing the exam

Multiple choice questions

Your best friend when it comes to MCQs is the process of elimination. Which
responses can you cross off? Just remember while you’re staring at the
question, scratching your head, the answer is right back at you so if worse
comes to worst, make an educated guess.


Short answer questions

There are several things to be considered when approaching short answer
questions; mark allocation, cognitive verb and biology concept. Here are some
simple questions you can ask when you are completing these questions.

Comparative Questions:
  • What does the cognitive verb require me to do in my response?
  • Similarities and difference or just differences?
  • What biology concepts are in the question?
  • Do they link? How?
  • How many points should I make? Look at the number of marks.
  • Have I used appropriate language to demonstrate the comparison?
Explanation questions:
  • What does the cognitive verb require me to do in my response?
  • What biology concepts are in the question?
  • Do they link? How?
  • How many points should I make? Look at the number of marks.
Stimulus questions:
  • What does the cognitive verb require me to do in my response?
  • What biology concepts are in the question?
  • Do they link? How?
  • Are there independent and dependent variables? Relationship?
  • How many points should I make? Look at the number of marks.
  • What data can I use to support my answer? Consider the marks.
Calculation questions:
  • What information have I been provided with?
  • What are the variables?
  • What is the formula?
  • What values do I need to substitute?
  • What units do I need to use?
  • What does the cognitive verb require me to do in my response?
  • Similarities and difference or just differences?
  • What biology concepts are in the question?
  • Do they link? How?
  • How many points should I make? Look at the number of marks.
  • Have I used appropriate language to demonstrate the comparison?

At the end

Timing is important in your exam. If you get stuck on a question, make a note
of the number, and move on so you can come back to it later.

Use your teachers

Your teachers are the best source of information & support and are there to develop
your understanding of concepts and help with writing your responses. They know
what they’re talking about. Ask questions, they will support you.

1

Make a plan

Preparation and planning are key to success. Make a plan, make it flexible, make it
targeted to your strengths and weaknesses.

2

Language is important

Biology is vocab heavy. Terminology is particularly important and there are many
terms that sound similar but mean very different things. e.g., transcription and
translation. Make yourself aware of these. Also make sure you know how to
pronounce terms, as this will help you to spell them correctly.

3

Set up a study space

Those final weeks before the external exam are crucial. Reorganise your study
space to remove all distractions and create a new mindset that your final exam
study is slightly different to the work you have been putting in throughout the year.

Enjoy Biology

Biology is the science that draws a lot of other sciences together and gives it
meaning through life. You are studying a subject that demonstrates how truly
amazing living things are. Enjoy what you are learning; you live by it every day.
