🎓 SACE SUBJECTS (Year 11 & 12) – What Most Students Get WRONG

🔴 1. ATAR comes from Stage 2 (Year 12)
Your final score depends mainly on your Stage 2 subjects — not Year 11.

🔴 2. Subject choice = future options
Pick wrong subjects → limited university pathways
Pick smart → more opportunities

🔴 3. Stage 1 still matters
Weak basics in Year 11 = struggle in Year 12

🔴 4. Don’t follow friends blindly
Your path ≠ your friend’s path

Proud moments ❤️🇱🇰💐

My last A/L batch in Sri Lanka was in 2022, before I moved to Australia in February 2023. Even now, in 2025, students are still reaching out to share their results after learning from the videos I created during the COVID period.

It means a lot that you remember me on such an important day, even though we haven’t met in years. That kind of impact matters more than anything else.

My blessings are always with you.🙏

I truly hope I will have the opportunity to support students in Sri Lanka again in the future.🇱🇰

An Australian scientist is one of three people who have been awarded the 2025 Nobel Prize in Chemistry "for the development of metal-organic frameworks".

Scientists Susumu Kitagawa, Richard Robson and Omar Yaghi laid the groundwork to potentially suck greenhouse gases out of the atmosphere or harvest moisture from desert environments.

Metal-organic frameworks are molecular constructions with large spaces through which gases and other chemicals can flow.

"Through the development of metal-organic frameworks, the laureates have provided chemists with new opportunities for solving some of the challenges we face," the award-giving body said in a statement.

University of Melbourne chemist Richard Robson has won the Nobel Prize in Chemistry!

Professor Robson, 88, was one of three scientists to win the Nobel Prize in Chemistry this year for their work in “the development of metal-organic frameworks”.

The Nobel committee says the discovery is capable of allowing water to be harvested from desert air.

He shares the award with two scientists from Japan and the United States.

Professor Robson has been a lecturer and researcher at the university since 1966 and has been working on metal-organic frameworks since the early 1990s.
