Hey, I was recently admitted to a PhD program, and I will need to catch up on some math before I go because I will have to take Calculus.
I was recommended the Khan Academy PreCalc course, but I would like to know how long does it usually take, and how many hours a day/week I should devote to it?
I hope I can get a response soon!!!!
Hello RichK,
Each unit will usually take 3-6 hours (watching the videos; reading the articles; doing the practices, quizzes, and tests). PreCalculus has 9 units, so about 27-54 hours total.
Before diving into the world of Precalculus, ask yourself these questions"
- How many hours a day/week can I use to study?
- Do I have a finish date? (When should I be finished going through the course?)
- Am I going to go through the whole course or pick and choose?
After answering these questions, you should be able to gauge how much time you should devote.
Hope this helps.
P.S. If you want to be more precise in your planning, I can create a list of the number of videos, video time, number of practices, articles, and quizzes for each unit. Just let me know.
