A physics coursework in school or college is an assignment that requires planning, research, analysis, and evaluation. Some students might be good at research, while others may like deduction. When physics coursework has to be compiled, the skills mentioned would need to be combined together to enable you to complete the coursework in time and to your satisfaction.
Grades are important in a physics coursework. The content therefore has to be interesting even though it could be technical and written to prove a theory. It is possible to achieve a reasonable score with your GCSE coursework. In college, advanced topics would have to be chosen. A useful method would be to gather coursework info from the internet and compare it with scores. Choose topics that have been getting good scores consistently.
Students find it easier to write an essay that is descriptive. It is possible to adapt to physics coursework that takes the shape of a subjective essay. For example, you could choose a topic for your student essay that deals with theory that needs to be established through experimentation. Suppose you choose to write on electricity and magnetism and zero down to electromagnetic force, you could establish notes on the theory leading to the sub topic. These notes can be compared in class and a connection established with the help of experiments. You need not include too many formulas or complicated charts. Keep it simple. Prepare an essay outline and try to explain with pictures and textual content.
To summarize, you start with a planned project. You can get help here, but try and create a plan yourself. After you have developed content for the coursework, try out the experiment to see if it yields the desired results. You may not get it right the first time, but that does not mean the experiment would not succeed. You may be missing an important element. Get help from tutors and forums and then try again. If you succeed, complete your coursework based on the revised plan. You could use an essay writing service to save time. Your physics coursework would allow you to gain valuable knowledge that would be useful to get good scores in your final exam.
