The tips begin at a different place in each module. The advice moves along with the stages of the course.
Content review is like exploring a city. Topic by topic, it's like exploring at the street level. You're at the coffee shop. Next a park. There's an office building. You reach a museum. The path through the city progresses in time, the coffee shop before the museum. If you're not careful, MCAT review becomes only the street level. How does the city look from the top of the tallest building? The coffee shop and museum are simultaneous. You see another path that starts at the museum and ends at the coffee shop. The two are together within a neighborhood, and there are other neighborhoods. You can see the whole city.
