FAQs About The Best Performing IB Schools In Australia
1. What is the best IB school in Australia?
MLC School in Sydney was named Australia's top IB School in 2020 and 2021. The school is also a Top 50 IB School on the global scale.
2. How does the IB programme work?
You choose one subject from each of five groups, including two languages, social sciences, experimental sciences, and mathematics. You also choose either an arts subject from a sixth group, or another subject from groups one to five.
3. Is IB harder than ATAR?
The International Baccalaureate (IB) is often considered more difficult than the ATAR due to its broader curriculum, additional components like the Theory of Knowledge (TOK) and Extended Essay (EE), and a higher overall workload over a two year period.
4. What is the IB equivalent of ATAR 95?
A 95 ATAR is generally equivalent to an IB score of around 39 to 39.5, depending on the specific conversion table used by the relevant university admissions centre.
For example, VTAC lists a 39 IB score as equivalent to a 95.75 ATAR, while the Universities Admissions Centre (UAC) shows a 39 IB score converting to a Combined Rank of 95.75.
5. How difficult is it to get a 45 IB score?
Getting a 45 on the IB is extremely difficult, as it is a flawless score achieved by fewer than 1–2% of students worldwide each year.
To achieve this, a student must score a perfect 7 in all six academic subjects and earn 3 bonus points from TOK and the EE by achieving an A in both.
