Recommended Study Guide  
C. Donald Ahrens (author) 
Study Guide for Ahrens’ Essentials of Meteorology: An Invitation to the Atmosphere, 7th Ed. ISBN-13: 978-1285834979. (Not available in bookstore.)
You must order through publisher or an online vendor. Cost is about $50.
I do not know if rentals are available through the publisher or online vendors.
Some students find the guide very helpful, but most students do not get it.

I warn that new and even used copies of the 7th edition are not cheap. Although I do not recommend using an earlier edition of the textbook, I am compelled to disclose that students in the lecture sections have used the 6th edition with great success. If you decide to save money and use an edition earlier than the required 7th, you are 100% responsible for matching equivalent subject matter in an older edition.

Bottom line: wherever you get the book and whatever edition you use is a personal decision. Just get the textbook. Now. There is a lot of meaty, required reading for this course, and it starts day one. The length of assigned reading averages approximately 80 to 120 pages per quiz.


 Do not fall behind the assigned reading.
If you do, you are likely doomed.
