Answer:
3. In a spiral notebook
Step-by-step explanation:
A spiral notebook is the most suitable option because this type of notebook helps the student to have all the notes and information in one single notebook, so the information can be easily located in one single unit and it can be more organized, which it's essential to improve study habits. Loose-leaf notebook paper and separate note cards are not recommendable because, with these papers, the information can get easily lost and disorganized.
