It is a high time to group all the ideas that you came up with. Cross out any irrelevant ones and make your best to put them into a logical order. When ready with your ideas, organise them into separate paragraphs. Keep in mind the following layout of writing: an introduction, a main body and a conclusion.
So if you are concerned about your writing skills, consider getting some help with things like paragraph structure, punctuation and grammar and spelling. Most colleges provide this free and you will also be able to find many free resources online. The first thing you need to be clear about before you start your essay is the type of essay you will be writing.
