For some subjects it’s alright to have only one day to review, such as English or History. On your own you should be able to review a book with the notes that you should have taken when you were originally reading the book. A subject like Math or Science can be a bit more difficult.
In the subjects Math or Science, if you don’t understand how to do something, it can be very confusing and complicated. Those subjects require teachers to explain steps and different methods to achieve the correct answers.
Picture a classroom of 22 students. Each student in that class has a different question for a different problem. You can imagine that 48 minutes of class time is just not enough.
Most teachers will stay on track with their normal teaching routine for the week, which does not help students. Midterms start on January 30th and review day is January 29th. A majority of students feel that with only one day to review with teachers they will not be ready for midterms.
Because of this students should make sure to go to extra help as much as possible to get the studying they need done. Even if it is for 15 minutes or an hour, it will help you and prepare you.
