Compare your new notes with the old ones

Compare the context of the new notes and your existing notes.
The information you’re adding to your collection of notes may already exist in it. If this is the case, compare the two contexts of the notes. This may help you understand the differences in the application of your information.

Make a new note about the crucial differences and label it.
Once you have identified the key differences, make a new, labeled note which describes the differences between the new and old notes. This will allow you to build a greater understanding of the concept.
