I'm in grade 9 , we just started parabola's and quadratic equations. I'm able to do quadratic equations no problem, I did do some parabola's a while ago so it would be practically revision. I did start Trigonometry in my own time I just finished the sin line.. should I still continue ? (We haven't started trig yet). After finishing what ever when can I start calculus ? Also with physics, I've done physics of motion up to projectiles flying through the air (briefly know it since I learnt from khan academy), and waves (strong). What should I start doing in physics and maths, I really like to expand my knowledge.. thanks!
