How do you tackle the science section that has a lot of questions and passages to get through?
First flip through the passages, and check categories each one falls under, noting down the type and subject. Tackle the ones you find easy and know more about first, saving the others for later. For easier passages, go straight to the questions first and look only at the passage and data related to the question. Isolating the data will help you focus only on the relevant information while also spending minimum time doing the questions. For passages that are rather text heavy, skim the information quickly and jot down simple notes that yield the end results or conclusions of what is discussed.
