This summer I plan to self study quite a bit and want to learn as much as I can. I'm an EE major and have taken Calc 1-3, and DiffyQ/Linear algebra as well as intro physics classes. I will be taking classical mechanics in Spring 2013 but wanted to dive into Griffiths E&M book this summer. Is this a bad idea? Will it be less efficient than the traditional route? Also, I have Boas' book to supplement any math deficiencies that come up. Thanks for any advice.
