How do you know how to study smart?
How do you know if you actually are studying smart? :L
Any tips of studying smart for all science and maths ext.1?
You need to have a clear plan on what you want to learn. Smart study differs from person to person.
For Physics it's pretty simple.
Make notes on each and every Syllabus dotpoint.
Memorise the key facts for the 'remembering' dot points and complete problems for the 'calculation' dot points.
Always rememver to state the formula(e) required and show the substitution line.
I'd recommend the Shadwick HSC Physics 'Dotpoint' workbook to test your knowledge.
After learning your notes and completing Dotpoint, practice past HSC papers. Look at the marking criteria for each question and relate it back to the syllabus dotpoint being tested.
I can't give any advice on Pracs, seeing as the marking criteria differs from school to school.
Maths is different. This is what I do for 3U.
I know MOST of the content in the 3U so I sit past HSC papers. I divide the exam into parts. Stage I Q1-5 and Stage 2 Q6-7.
Each Stage has 50 minutes working time and 5 minutes reading time (for both stages). Pass mark for Stage 1 is 58/60. Pass mark for Stage 2 is 21/24 with the total pass mark being 79/84. The normal 3U HSC is 2 hours, so you have 10 minutes time to look over your work and fix up any mistakes. Keep doing papers until you're consistently passing. If you can't do a question, skip it. 3U is about speed. You can come back to it later. If you're consistently getting a particular topic wrong, work on textbook problems. ALWAYS MARK YOUR WORK.
4U, I'm not going to give any advice other than 4U=Care.
tl;dr Phys: notes on each dot point, memorise.
3u : Past papers, 2 stages, pass is 79/84 or higher. Speed.
4u : Care
