Revise What’s HARD: Focus on Electrolysis

VCAA VCE Chemistry how difficult is each topic
Click to download PDF version. Numbers in parentheses denote Chapter numbers.

The VCE Chemistry examination is only 22 days away. As you complete at least one practice paper each day and correct them ccording to your revision timetable, you’ll be finding that you’ve already mastered certain topics while others remain difficult.

Patterns emerge in student readiness: each year, electrolysis is the worst-studied topic on the course. Because VCAA has a reputation for asking questions on topics that students repeatedly got wrong in previous years; I decided to test this hypothesis by getting real data from recent examination reports and displaying it on a scatterplot of:

  • how difficult each topic is (% of marks lost) on the x-axis
  • how often the topic is asked (marks per paper) on the y-axis

The results were fascinating. While it’s impossible to say with any certainty which topics will be on the examination this year, previous years’ examination papers have placed more emphasis on the difficult topics (electrolysis, Ka, redox and biofuels). Focus your revision on these topics again this year.

Conclusion: Focus your Chemistry revision this week on your least favourite topics… those topics will probably be worth more marks in the examination!

How to Deal with Exam Stress

It’s that time of year when students are starting to plan their exam revision. Getting to grips and memorising all you have learn over the past year is only half the battle, as new research from productivity website Stop Procrastinating has found that 64% of students believe that exam stress and anxiety is affecting them so much that it will lower their performance and affect their grades.

The poll of 2000 undergraduates heading into their final exams found that 66% of students believe their stress levels are greater than in the past due to modern day problems, such as the difficult jobs market. They feel that a lower grade could affect the rest of their lives, closing doors to opportunities and causing them to miss out on jobs.

The survey found that procrastination was a major cause of stress. Students today have more opportunities for distraction with the rise of the Internet, smart phone and social media. A massive 45% of students surveyed said they wasted time on the Internet or social media instead of revising.

There is good news, however. The survey also found the strategies and solutions that students find most effective. By using Internet blockers while revising, taking more exercise, and by breaking down revision into manageable, bite sized-chunks, students are finding ways to cope and succeed.

The full list of effective revision strategies is available at Stop Procrastinating’s website here.

Annotated VCAA Chemistry Data Booklet

The VCAA Chemistry Data Booklet contains answers to many questions you’ll be asked in the end-of-year examination. Unfortunately for students, however, the information it contains is neither explicit nor complete. Students need to know how to use the data booklet if they are to make the most of it.

Many formulae and definitions still need to be learned. For example, the data booklet doesn’t give you calorimetry formulae, and hydrogen bonds aren’t shown on DNA nucleotides. Trends are missing from the periodic table, and the electrochemical series comes with no annotations whatsoever! All this extra information needs to be memorised for VCE Chemistry.

I’ve annotated a real VCAA Chemistry Data Booklet to help you understand it. You can download it here.

Features include:

  • Trends are now shown on the periodic table (page 3);
  • Electrochemical series is fully labelled and explained (page 4);
  • 17 equations and 4 gas laws are given on page 5;
  • NMR data is now labelled to help you identify functional groups (pages 6 & 7);
  • Infrared absorption data is now pictured with 3 peaks described (page 7);
  • Amino acids are now labelled “polar/non-polar” and “acidic/basic” (pages 8 & 9);
  • Number of C=C bonds is now included for fatty acids (page 10);
  • DNA structure is explained in much more detail (page 10);
  • Colours of two indicators are corrected (page 11);
  • Ka is explained (page 11);
  • Solubility rules are added on the back.

The 8 Benefits of Home Tutoring (VCE Chemistry)

VCE Chemistry home tutoring MelbourneIf you’re looking to boost your Study Score in VCE Chemistry, you should consider hiring a home tutor. Home tutoring provides quality contact time that often isn’t available in school. Home tutoring has eight main benefits:

1. Students get a thorough review of what they’ve learned in class with a home tutor

Studies show that a student who leaves a class without having made any notes is able to recall about 10% of what was taught as they leave the classroom. Spaced repetition reviews with a home tutor can increase memory recall of knowledge being taught to well over 80%. By remembering more of the course content, students are primed with a foundation to understand and apply that knowledge much more easily.

Tutors can also explain concepts much faster and more succinctly than teachers in the classroom because they’re working in a one-to-one environment. Without distractions, and without having to divide their attention between 20 or more students, a home tutor can explain clearly in ten minutes what might take a whole lesson if taught by a teacher in a classroom.

2. Students are more motivated to do their homework with the guidance of a home tutor

Students who work on homework tasks with a home tutor tend to stay focussed for longer periods of time than those who don’t. With a home tutor, students can ask questions while doing their homework and spend less time getting ‘stuck’ because they get instant support when they need it. Home tutors can also question students and ask them to explain the answers they’ve given to check and consolidate understanding.

A tutor can also break down even the most complex homework questions into a series of simpler questions that the student is able to complete. With home tutoring, students complete their homework assignments on-time and always to a very high standard.

3. Students can pre-learn what’s about to be learned in class before a topic begins

Imagine walking into a classroom already knowing the gist of what you’re about to learn. If a student learns a new topic with a home tutor, the classroom environment becomes the place for revision rather than first-time learning. Learning a complicated subject like VCE Chemistry is far more efficient this way. Probably the greatest benefit of pre-learning with a home tutor is that students can then make a great impression among their teachers and peers by grasping ‘new’ concepts extremely quickly in class, which gives them a huge confidence boost in the subject!

4. Students receive adequate homework tasks

Not all schools set enough homework tasks. You can ask your tutor for more homework questions. Unlike most classroom teachers, a home tutor knows your student’s exact strengths and weaknesses in the subject with great detail, and can select homework questions from a wider range of sources to help your student improve on the exact topic areas where they need more practice.

5. Students receive very, very detailed feedback on their written answers with a home tutor

In a VCE Chemistry examination, writing “the solution decolourises from blue to colourless” might earn one mark, whereas “the solution loses some of its colour” will not. Labelling ethanol in a combustion equation as “liquid (l)” might earn one mark, whereas “aqueous (aq)” will not. A classroom teacher marking dozens of tests can easily miss the subtle nuances of language that VCAA examiners are be looking for, or might not have the time to explain exactly why a question was answered incorrectly to each student in a class.

Home tutors can examine, question and correct every answer the student givesno matter whether it’s written or spoken—and provide instant feedback on the student’s responses as they work. Instant feedback is very motivating and time-saving for students.

6. Students get a second voice explaining new concepts

If the class is quite large, or if the teacher has a heavy accent, not all students will understand all of what the teacher is saying. Home tutors can explain the course concepts one-to-one in a quiet, home environment, which is efficient, engaging, and is always done in a way that the student understands.

7. Students get an extra set of textbooks

Home tutors always coach students from different schools. Hiring a home tutor allows you to gain access to a second set of textbooks, past paper examinations and practice materials from that teacher, which your current school might not have access to.

8. Students get meta-study tools from home tutors as well

Home tutors do more than just review content, help with homework assignments and pre-teach upcoming topics. They also provide students with:

  • personalised examination revision timetables
  • examination tips
  • thorough notebook checks
  • general study tips
  • note-taking strategies (e.g. Cornell)
  • reading strategies (e.g. The Reading Process)
  • and more… 

The benefits of home tutoring allow the student to maximise their potential in homework, tests and examinations not only at VCE level, but throughout all the years of university as well. For as long as a student is sitting some kind of examinations, the student will be using above the strategies that a home tutor can provide.

As a VCE Chemistry and Physics teacher, I can testify that students with regular home tutoring are generally happier and more focussed in class, pursue their homework tasks more thoroughly and gain higher scores in tests because they’ve had the one-to-one time required to learn all the subtle nuances in language that examiners are looking for.

The 2 Ingredients of Excellent Exam Revision

Source: Christian P Walker

If you’re in high school, you should spend about two thirds of each day studying for six days each week for several months before your important exams. But apart from doing the required homework, what else should you be doing in that time?

Answer: Just 2 things.

(1) Make great notes.

Make them, re-make them and then make them again. Make them clearer and more beautiful every time. Organise them according to the official study design (or “syllabus”) for your course. Put your notes on the wall of your bedroom or study. Take some of them down temporarily and see if you can recall them by heart.

You can buy books of theory notes online, but the process of making your own notes is when most of the theory learning actually takes place. Use those purchased books for inspiration only. It’s okay to use a computer to make notes, but do at least one hand-written version as well. Become a pro at hand-writing explanations and sketching diagrams with a pen. This experience will save you time in the exam.

(2) Do lots of practice questions.

Get practice questions from as many sources as you can. Use real past papers, use past-paper-style questions from companies, and if you need more, do questions from the textbooks your school isn’t using. Complete these questions first without answers, then refer to your theory notes if you get stuck. When done (or if completely stuck), check the answer key or send an email to your teacher. Do all of this in one study session.

That’s almost all there is to it! I’ll post more about each of these two instructions in the next two weeks. Making great notes and doing lots of practice questions are the two most important parts of exam revision.
