In Sixth Form Business courses, it is important to be able to write in detail, explaining your points using application, analysis and evaluation (where necessary). 

You need to understand how much detail is needed for different types of answer and be able to write 'chunky' paragraphs (at least a third of an A4 page) in order to write at the level required. 

Essentially, longer written questions tend to be either: 

a) Analytical/Analysis questions eg Analyse...., Discuss..., Why...

or b) Evaluative questions eg To what extent...., Recommend...., Evaluate....

Good answers to both of these type of questions tend to be structured quite similarly. 

Answering analytical questions

Analytical questions generally require 2 main points/paragraphs (try to have each paragraph focused on a single point). 

Each paragraph needs to go into detail about your point. Analyse in business, essentially means consider the questions how and/or why. 

For your paragraphs, consider using PEEL (my preference) or PECAN PIE (contains similar elements). 

Application

Often in business courses, there is a need to 'apply' your understanding of a topic to a particular business or business situation. You have to do this if a particular business is named in the question, or even a particular type of business. Try to make sure you are writing about the specific business in the question. The "MacDonalds rule" is useful to think about to make sure you have done this. 

This is also the CAN in PECAN PIE. 

The MacDonalds rule is that if you can replace the name of the business in your answer with MacDonalds and the answer still makes sense, then you haven't applied your answer to the business in the question.
