Once you feel that you understand what you have to do, you should make a plan.
In the plan, break down your assignment into tasks (steps) and allocate time to spend on each of these tasks
The tasks will be:
Think about how much time you need to allocate to each task. Researching & note-taking should take around 40% of the the time available and writing & editing around 60%.
Even if the deadline seems like a long way away, start planning and organising your time as soon as you can; you don't know what is going to happen in the future!.
Include some time between finishing writing and starting editing. Give yourself plenty of time to make changes if they are required.
On whatever device you are using, create a folder for your assignment to keep your electronic notes together. Do the same for your paper notes - use a ring binder or folder.
Consider downloading and installing reference management software to keep track of the sources that you will be consulting. The library recommends using Zotero (more information about Zotero can be found here)
