How to Do Well in the HSC Sciences

Performing well in HSC sciences demands a slightly distinct approach than HSC maths or English subjects. HSC sciences, like Chemistry, Physics and Biology, location a heavy focus on the syllabus. Detailed knowledge and familiarisation of the syllabus is very essential.

TIP 1: Know the syllabus

Knowing the syllabus extremely essential. Firstly, all HSC science exams can only test you on content within the syllabus. Most of the time, HSC exam questions will merely be a syllabus dot-point that has been reworded.

For example, an actual HSC Chemistry syllabus dot-point is “Describe hydrogen bonding between molecules”. A corresponding exam question can ask something easy like “Describe hydrogen bonding between water molecules”. Alternatively, exam questions can be slightly more complex, for example: “Identify a compound that exhibits strong hydrogen bonding and descbribe how hydrogen bonding affects its melting and boiling temperatures”. Nonetheless in both instances, the question can be reduced to merely describing your understanding of how hydrogen bonding works as between molecules, and how this phenomenon affects some of the chemical’s physical propertie(s).

All of nature has a rhythm. Birds fly south and the leaves of trees changes color as if following some mysterious cue from a master timekeeper. We are no diverse. Our bodily functions and our brain follow a definite rhythm. This affects our thinking ability and mental capacity to bear in mind and concentrate.

At specific times of the day, our rhythm reaches a peak, even though at other times, it is low. Our body temperature fluctuates according to this rhythm, as does our blood pressure and the level of specific hormones in the blood. Our body’s functions according to a fixed time plan, which is slightly various from person to individual. Our every day rhythms are dictated by the rotation of the earth around its axis every single 24 hours. Nonetheless, our biological clocks run slightly slower than the earth’s rotation’ for most people, an inner day has about 25 hours.
