How to use sticky notes
Mark your book.
Sticky notes are great for marking pages or passages in a book you are studying. Just stick the note on the relevant page and maybe write a brief note or a few key words that indicate why you have marked this section.

Options are: 1. For example, if you are drawing a case that contains the word " organism " and " the vast portal of the rabies virus, " designate that section " organism " as " undertaking to study on opposite sides of the same page. This way you can identify the location where sticky notes from real plants are often placed. 2. As well as the traditional square sticky notes, you can purchase slim and tall ones which work particularly well to mark pages in a book. These slimmer notes will mark the page without covering over much of the actual text. 3. A sticky note will provide you with a visual reference to the book or text you just picked out. Keep in mind though, that your sticky notes will need to cover several blank pages or passages. 4. You can provide the same strategy by adding notes to a text to help you study. Scoring one point on a text means your notes will be taken and fully absorbed by the reader.
