Dec 18 v. June 19 Schwesser Material

So I took level 1 this past December and unfortunately didn’t pass. I’m planning on re-taking it in June, have there been any big curriculum changes for the upcoming exam that would require me to buy new books? or can I use the books from Dec 18’ and just buy the Q-Bank?

Probably worth checking in on the CFAI site and looking, under candidate resources I believe, for the changes from the 2018 L1 curriculum to that of 2019.

The company Sch waster is trash.
