The good news with this question is that you are thinking about it PROACTIVELY. Ultimately, avoiding the need for academic recovery is effectively asking the question “How does a student truly master their material?”
Your student has to hit the ground running at the beginning of the semester. They should have begun to take a look at the material to be covered before school starts. I work with a number of students BEFORE the semester begins.
There is a plethora of internet resources available to get a head start. Get on my mailing list (scroll down to the bottom of the page to sign up) and request a time for us to chat. Knowing the specifics of your situation will help me find the prime area to focus on. Generally, students suffer from one or more of the following: 1) not really knowing how to do research, 2) not having a high bar to reach for, 3) lack of consistent habits, 4) not knowing how or when to take effective notes, 5) motivation, 6) poor foundational skills, and others.
