It takes some work. You have to understand, first and most importantly, what is being asked of you. You must familiarize yourself with the requirements, know what it is the tutor is looking for and wants. Usually, the learning outcomes or objectives related to the assignment can give you some clues. As well, you must actually read the assigned readings and go beyond that to include your own research. And then you have to bring it all together. What does that mean? Well, to start, you have to use the readings to answer the question or address the requirements, relate it to the lectures and information taught in the module, always remain critical (look at all sides of an issue), and write clearly, concisely.
