Hello PF, I'm going to be heading to my 3rd year as a Physics major and I want to make this last month of summer a tad productive. So my plan was to review/self study math using the mathematical methods book by Boas (and maybe some online resources to get more depth on some particular topics). Is this good idea? and if so, is there a recommended order that I should do the topics in to better prepare me for my 3rd year? Thanks for all input !
