I have a test in 4 weeks a little help!!!!

Hello i have 4 test's in 3-4 weeks but the main one im worried about is physics. Im in a levels and currently 16 turning 17 in jan, Some of the physics's is really mind blowing to me... How should i revise it? so far i've gotten two E's lol in my practice papers.. so im a bit stunned if you know what i mean.. how should i revise for it and balance revise for 3 other subject's as well?! thanks any info or tips much appreciated.

You should review the physics. There are far fewer laws of physics than equations. If you memorize and understand the physics, in plain language, you should be able to derive whatever equations you need to solve problems. And when you can derive the equations in your textbook and notes, you will have learned the physics.

I'm not suggesting you derive equations during the exams. You won't have time for that. But derive them as you study for the exam. That will firm up the physics from which those equations come and give you a good basis for not only using those equations, but for deriving further equations which you may need to do during exams.

As oldprof, I always included questions in my exams that required the students to derive what they needed to answer them. That was my way of finding out just how much physics they knew...as opposed to memorizing equations and having no real clue how to use them.

Read all of your notes and the Physics textbook that you have. If you do not have a textbook, then buy one or borrow one from a library. Practice the questions that you find in the textbook and any that you find on the internet.
