You can expect a significant amount of memorization and prior understanding of key topics and vocabulary. If you don't understand something, it's usually simpler to acquire the knowledge from other sites/peers, as his approach of assisting students is going around the class one person at a time, rather than going to individual students who want assistance. If you don't have any prior knowledge of previous units before the grade, it won't harm to go over those things again because it will be quite beneficial in the future. The students that have stronger visual/spatial intelligence and can exhibit strong listening ability are the ones who I found to be the most effective in the class.
