For Leaving certificate Physics, we have to study the following topics
Vibrations and Sound
Op - Particle Physics / Applied Electricity
I would recommend you to go to youtube, and search each topic and see some videos to understand the concept. It really helps when we actually start studying. The animations will stick in to our mind , and will be helpful.
keep up to date with your studies ie if your teacher goes through a topic in class and gives notes or not( you can go on physicsteacher.ie for notes) go home and learn those notes off, doesnt have to be word for word but make sure to not paraphrase key words, in terms of the maths parts, when your teacher tells you to do maths physics work, do the questions assinged and ask if you don't get the question
Do sheets for your experiments, focusing on the types of questions that come up in the exam. Have the questions and marking scheme open so that you can see what they will ask, the questions for each experiment are practically the same every time they come up, so if you revise it well enough you'll have at least 25% just from experiments. Also spend time on the demonstrations, definitions, and derivations. Anything you can learn off, do it! You don't want to lose marks in questions that you just need to learn the answer to.
