Due to its definition, human error is one thing perform. Within the more quantitative HSC subjects for example Mathematics, Physics and Chemistry, human error could be a big reason for losing marks in exams. For instance, how frequently have you ever left of the exam room, and understand only moments later that you have lost a couple of marks inside a question or more because of ‘silly mistakes’? Or when, appearing out of a test room, you talk to your buddies about how exactly they did question X Y Z etc and realising you missed a small detail that set you back marks? This occurs very frequently for a lot of students, and the simple truth is, human error transpires with a lot of students, the top ones.

Common places to create ‘silly mistakes’

In HSC exams (in addition to assessable school exams, because they are all much like HSC exams), students mainly make their silly mistakes inside a couple of ways:

Lengthy, complex algebraic proofs (e.g. lengthy proofs in Maths Extension 2, making you copy the prior line’s expressions incorrectly)

Lengthy calculation-based questions requiring lengthy working-out and calculator work (e.g. molar calculations in Chemistry)

Multiple choice section in science exams

It is extremely impossible to create a ‘silly mistake’ in humanities-type subjects like British, or perhaps in the lengthy-answer parts of science exams within the same ways as individuals described above.

Look at your work once you finish

Since there’s merely a couple of situations where silly mistakes can be created, students ought to be conscious which regions of their exams they have to check over whether they have free time close to the finish of the exams.

Generally, you’d have only some time left once you finish your exam. Therefore, it is advisable to understand how to best prioritise your time and effort in looking for mistakes prior to the exam time expires. This really is presuming you’ve already done the questions – if you have left some questions blank, clearly finish them before beginning checking your projects.

Physics and Chemistry exams

For science exams like Physics and Chemistry, once you finish your exam, you need to first look at your entire multiple choice section (the very first 15 questions). A great way to do that would be to hide the way to go sheet, so you don’t visit your original solutions, reducing their influence. Seeing your original solutions is not recommended, because they is going to influence you into making exactly the same mistake while you first did. Hiding your original answer can make you psychologically perform the question again on your own, and increases your odds of obtaining a mistake that you have missed inside your first attempt for the questions.

While you perform the multiple choice section the very first time, it may be beneficial to circle the questions that you’re unclear about (around the question sheet), to ensure that whenever you finish your exam, you should think about the circled questions first.

Once you completely check over your multiple choice section, go over your calculation questions. In Physics, this can be questions involving projectile motion, Special Relativity (time dilation, length contraction etc), motor torque, forces on billed plates / conductors / billed particles etc. For Chemistry, these questions might be molar calculations, pH calculations, volume calculations, galvanic cell potentials etc.

Some topics in Physics might be aided with methods covered in Mathematics subjects. For instance, within the Space module, we learn to do projectile motion calculations – these questions tend to be simpler when analysed inside the Extension 1 framework of projectile motion. Obviously, it might be faster if you are using the formulae within the formula sheet, however for checking purposes, you should use the Extension 1 approach to verify your solutions.

Not every student understands the concepts of chemistry in the classroom, especially when the teacher is rushing from a chapter to another. If you are one of them, consider taking JC chemistry tuition for added assistance from the best tutors.
