Hello everyone. I have few questions to ask you, and I hope you help as much as you can. First, I'm high school student in Tunisia (final year/Baccalaureate) and I want to prepare myself in an excellent and remarkable way for the Test ( which includes physics of course ), and the problem is (as you may expect) that I don't have a solid foundation (or basis) in physics that I can build upon it later on.So, in the class (or even when I try understand something by myself) I find myself questioning about everything and even though I understand most of the time that still not satisfies me. I've always had that fear, that I wouldn't know everything about a particular subject in that particular time. So, I said why not buy some books and try to come back to the basics, study them in about 1 month period (I don't have much more) and then move on and maybe take an edge on my classmates. I'm the kind of person that even if I understand something, I am still confused because I don't know the things that it is based on them.That's my philosophy about learning things, and I've paid a huge price on it( I'm 21 and still in Terminal Secondary School). I bought 2 books: Physics I for dummies & Physics II for dummies. I've begun on Physics I and I've come until chap 3 now. Until now everything is about motion, speed, velocity, acceleration...It's quite easy.BUT, the problem is that I don't study those subjects these year in class: Here's our Program in Physics: (Note that I study Physics, Mathematics and everything else in French at school, but that's not a big problem) Part I: Evolution of Electric Systems 1- RC Circuit. 2- RL Circuit. 3- RLC / Oscillation 4- Signals Part II: Waves Should I study the things I probably don't need so much ( Motion, Forces, Energy ...) and then continue and Study what I need ( Electricity, Magnetism, Waves...)? Or I have to change my plan completely? I 've set a deadline to complete, Dec 31 2014, so I would be up to date with my classmates after holidays, what do you think? Give me as much advices as you can. Ah, For chemistry I bought Chemistry: Concepts and Problems and I completed the first 2 chapters.
