What is your child planning to do after school?

It is a good idea to consider potential career paths before choosing HSC subjects.

This will ensure they are:

1. Meeting the prerequisites for university

Schools encourage students to choose subjects according to their preferred university degree. Students can avoid the excess stress of completing a ‘bridging’ course during university.

For example, most engineering courses require an assumed knowledge of 3 units of HSC mathematics and 1-2 HSC science subjects.

Many children will have some uncertainty around their life after Year 12.


It may be a good idea to narrow down to areas they are interested in and help them find relevant courses accordingly. Most of the time similar disciplines will have similar prerequisite requirements.

There are many career pathway quizzes online where students answer a range of questions  to calculate career areas or roles they would be suited to.

Many schools have a careers department or person that students can visit and have a chat to and explore potential courses. If not, you may ask the school for any relevant resources. The University Admissions Centre (UAC) has an annual guide with all the up-to-date courses, cut-offs and perquisites provided by universities.

HSC Careers Expos are packed with information and resources for HSC, University, TAFE or other courses.

This will give your child the interactive opportunity to ask questions from people working in the field or studying the courses. They will also be able to ask questions about subject choice and get a feel for the course and university they may be interested in.

Many schools allow students to attend Careers Expos from Years 10-12. If not, you can research events in your city that your child may attend.

2. Exploring other pathways

Your child may be considering potential future pathways through other methods of senior study.

Should I consider scaling when choosing HSC subjects?

Ida Ajdari, Business Manager and Head Tutor at Sigma Education reveals many of her senior students use scaling to boost their ATAR.

“Let’s say students get 80 in environmental science and 80 in chemistry, the school will typically scale the chemistry higher as it is considered more difficult, and bump up the ATAR. “

She does advise the most important factor is to consider the students personal interests.

“If they don’t work hard or enjoy the subject, a high scaling subject would instead bring their ATAR down. Scaling won’t interfere with them doing well. They should choose a subject if they are passionate and know they are going to do well.”
