I'm writing this 4 page essay for college on a swot analysis of a company, I've got the bulk (strengths weakness, opportunity and threats ) but I don't know how I will add sources in apa format (I don't even know how to APA) I also don't know how I will do the thesis statement and the conclusion, what should I include?
