ive had a really bad teacher for physics who doesnt even teach properly and was gone for almost a year and im now in 6th doing my LC next year. How can i teach myself physics? what can i do? will this affect my grades?
For me, I write notes out of my physics textbook and constantly practice the exercises that are in the textbook. Also, I suggest you could use mathsphysics.com because it helps a lot for the experiments. Link: http://mathsphysics.com/
They are pretty repetitive so don't worry too much. If you really don't like the subject then a good way to learn it is to just keep writing whatever notes and exam paper anwers as you can and eventually it will be embedded into your soul.
you seem really stressed so if you want i'll send you my school notes after november. i went through each set of notes and wrote down as many questions as i could think of. i practised answering them daily until i'd get them all right and then i'd move onto exam questions to make sure i'd be able to answer them all. don't waste your time making notes if you don't get notes at school, just go through your textbook chapters and make questions for relevant information. it takes way less time and helps it sit in ur brain better imo.
I'm literally in the same situation with having a bad physics teacher, and I know this is an option which involves money, but I enrolled in the physics course for Grade Academy and I learned more there than in the last year in school. It was definitely a worthwhile investment for me, maybe it will help you too. At least you can try the free trial. https://www.gradeacademy.ie/
You should try organic chemistry on youtube great for maths, physics, and chemistry just watch the videos take notes and use your textbook to practice excercises. If you are getting right answers should be set. remember have a growth mindset always improve hardwork and effort pays off.
