Actions to Implement Throughout the Year in the Lead Up to the QCAA Chemistry External Exam

As you’re studying content for the subject throughout the year, there are various things you can do to start preparing for your final exam. Following these 7 steps can be very helpful!

Actions to Implement when studying for Chemistry External Assessment

Step 1: Create a Revision Table Using the Syllabus Dot Points

Following the example below, the first column consists of a topic from the syllabus (e.g. factors that affect equilibrium). The second column consists of the subject matter dot points under that particular topic (number of dot points will vary โ€” this can be a good indication of how important a topic is!).

The third column consists of the actual content that is covered by the associated subject matter dot point. You can make this section much more detailed, by including pictures, diagrams, tables and links to websites or videos.

Finally, itโ€™s not evident here, but it would be good to also include a fourth column consisting of example questions relating to each subject matter dot point.

Create the actual table during the holidays before you start each unit. Once you start the unit, fill out each section as you cover it in class. This can also be an excellent way to identify any gaps in your knowledge!

Step 2: Make a Weekly Study Timetable

Of course, things come up in life and youโ€™re not always able to stick to the plan. However, it is important to have a general guide for yourself.

How much study you need to do for each subject is different for every student. For QCAA Chemistry, however, at least 3 hours of study a week (outside of class time) is ideal.

Some weeks you may need to do a little more, and some weeks youโ€™ll find that you donโ€™t need the 3 whole hours to go over the content. In this case, use the rest of the time to revise previous topics โ€” which leads us to our next step!

Step 3: Have Regular Study Sessions to Revise Previous Content

As previously mentioned, you may be required to recall information during the external exam that you first learned up to 12 months prior. This means that cramming before the exam won’t work!

Instead, utilise shorter, more frequent study sessions to improve the chances of the information depositing in your long-term memory. Along with this, ensure to go back and revise earlier topics throughout the year to consolidate your knowledge.ย 

Step 4: Review Content You’ve Learnt After School

Review what you covered at school each day after coming home to consolidate your knowledge and identify any gaps you may have. Ideally, review each concept within 1 hour of learning it, again within 24 hours of learning it, and then again within 1 week of learning it.

This method drastically improves active recall abilities and means you donโ€™t have to relearn everything three weeks before the QCAA Chemistry external exam.ย

Step 5: Make Diagrams, Flow Charts and Graphics Your Best Friend

Donโ€™t hesitate to use diagrams, flow charts and pictures to help you understand things. This is especially useful in Chemistry, as you will be learning about a number of different processes and structures which will require visual representation.

It can also be much more engaging to study a diagram as opposed to simply reading paragraph after paragraph. After all, a picture can tell a thousand words! See examples below:ย

Step 6: Clarify Any Uncertainties ASAP

This is important as you donโ€™t want to accidentally learn something that is incorrect, especially if it is a basic concept that is going to be built on later.ย 

So as you’re studying for the QCAA Chemistry external exam, if you have any questions about the content, try to do some research on it and if you still need more clarity, you can ask your teacher the next time you have class!

Step 7: Complete a Range of Practice Question Styles

If thereโ€™s a style of question you find yourself struggling with, then itโ€™s the style of question you should be doing the most practice on.ย

How to Prepare When There’s Only 2 Months Left Until the QCAA External Exam

Tip #1: Make sure you are well rested leading up to the exam

For the external exams, not only is understanding the content important, but so is being in a good mindset. If you put in the hard work earlier in the year, leading up to the exam you can focus on improving your mental health (e.g. getting better sleep, meditating, spending quality time with friends and family) so that you are ready to face the exam.

If you have learnt all the content and only have to revise in the weeks before the exam, thatโ€™s one less thing to stress about.ย

Tip #2: Get feedback on your answers

Get your teachers to read your answers to practice questions and get feedback on where you may be losing marks. You can even create your own questions using the syllabus subject matter dot points.ย 

Tip #3: Don’t memorise formula provided

Remember, youโ€™re provided with a formula and data book for the exam, so donโ€™t bother memorising things that you can already find in there.

Alternatively, get used to referring to the booklet and gain a rough understanding of where in the booklet you can find certain things (i.e. the list of acid-base indicators is towards the end of the booklet, whereas the formulas are at the start).ย 

Tip #4: Don’t be afraid to reach out for help!

Ask your friends, teachers, parents or school for support when you need it. Donโ€™t wait till you feel like youโ€™re reaching a breaking point to reach out and remember to check in with your friends too.ย 

Tip #5: Complete a practice exam

Once youโ€™ve covered a wide range of practice questions, try doing an actual practice exam.

At first, you might not complete it under timed conditions, and you may have your notes with you. However, once youโ€™re comfortable with this, it is important to try completing the practice exams in as close to real exam conditions as you can get.

Really try to simulate exactly what it will be like on the exam day: silent, timed conditions, and a fresh formula booklet (not the one youโ€™ve been using all year with your extra notes scribbled on it!).

The point of replicating the exam is so that you know exactly what to expect going into the examination room โ€” no surprises and no distractions from doing your best!

The Day Before the Exam

The day before the exam should be purely relaxation oriented. Make sure you get a good nightโ€™s sleep and have everything that you need for the exam organised and ready to take with you in the morning (pencils, pens, calculator etc.).

Light revision is fine but try not to cram any serious study as this will only make you more anxious!

During the Exam

Exam setting

#1: Ensure to read every question carefully

A useful technique is to underline the key parts of each question and make a little mental or physical note of what steps are required to answer the question. Also make note of the cognitive verb that is used in the question, as this will let you know exactly how to answer it.

If you want to know more about cognitive verbs and their meanings, check out the QCAA Glossary of Cognitive Verbs here!

#2: Remember that the multiple choice questions are only worth one mark each

So donโ€™t spend too much time on them. You have a 25% chance of getting them right even if you guess, so youโ€™re better off allocating more of your time to the short-answer questions!

#3: Estimate how long you should spend on each section

Make a rough timeline as to how many of the questions you want to have finished by a particular time (e.g. โ€˜I want to be finished up to question 10 by half-time, as the last 5 questions are worth more marks and will take longerโ€™). Make sure to refer to and stick to this timeline throughout the exam so that you donโ€™t unknowingly run out of time.ย 

#4: You donโ€™t have to complete the questions in order

It can be good to smash out the questions you are confident with first to ensure that you can bank those marks, then come back to ones that you are less sure about later.

#5: Your length response is determined by how many marks it’s worth

Use how many marks a question is worth as a guide to how detailed your answer needs to be and/or how long it should take you to answer it.ย ย 

#6: Double check your answers with calculations

With questions that require calculations, once you have the answer, ensure that you write the correct units (if applicable).

Also, stop and think to yourself if the answer you have arrived at is reasonable. If not, go back and check if youโ€™ve made an error in your process or calculations!

After the Exam

Make sure to congratulate yourself for getting through Units 3 and 4 of Chemistry and the external exam; it is no small feat!
