We all remember the endless ‘cells’ questions at the end of the 2014 Chemistry exam. Less memorable was that the 2013 examination awarded a similar number of marks for ‘cells’ knowledge. Exams that test knowledge of these last two chapters in the course (Galvanic Cells and Electrolytic Cells) separate good students from great students because these topics are taught at the end of the course when students are getting tired and teachers are rushing to finish the course before trial examinations and the Term 3 holidays. Only the most diligent students go out of their way to get a complete understanding of these topics at this stage in the year – and they’re the ones who benefit from this type of exam.
Interestingly, in 2013 and 2014, 33% of the marks in the VCE Chemistry examination were awarded for knowledge of just four of the textbook’s 28 chapters. Therefore, if you’re short of time, focus your efforts on these four chapters (28, 27, 16 and 12) before working on the rest.
“Based on past examinations, students should focus their revision on Electrolysis (28), Galvanic Cells (27), Equilibrium (16) and Biomolecules (12) before working on the rest…”
While the structure of past examinations provide no guarantees about future examinations, it’s still reasonable to expect that the top 5 subjects will remain mostly the same in 2015 as in previous years.
Correlation of the total number of marks awarded per chapter is moderate with R² = 0.48 for 2013 and 2014.
