Mine is split up for one page of motion, 1/2 page for special relativity, 1/2 page for electronics. It's typed and I set the font-size to 9. Any smaller than that is too small really.
Currently on motion I have a few equations (mainly just derived gravity equations, circular motion etc.)
I also have definitions for each type of graph (e.g velocity-time, net area = displacement, total area = distance, gradient = acceleration).
That stuff takes up about one-fifth of a page. The rest of the first page will be example problems from trial exams.
On the second page:
Special relativity - Mainly just definitions that will help me eliminate possible answers from the multiple choice questions straight away, but I do have a few equations, a table of Lorentz factors and one example problem for simultaneity.
Electronics: Mainly definitions, if I have space left I may put in a worked problem.
Oh yeah, I also have in the header and footers: "Reread The Question, Highlight Key Points" and guidelines for worded questions and counting the area under a graph.
Worded Questions:
- 3 to 4 points
- Explain Background Science
- Address the Question
- Conclusion
Counting Squares (approx): Number of Full Squares + ½ Number of Cut Squares (My teacher told us this, I thought it was kind of dodgy but it works pretty well in all the questions I've done so far)
I've tried to keep the information minimal and maintaining ease of readability.
Also, I noticed on your cheat sheet, soopertaco, that your equations are just quite low-resolution images (though it might be easier to read when printed out). You might find it a lot easier to make use of the Microsoft Equation Editor in MS Word. It makes equations nicely formatted and that much easier to read.
