Honestly, I am finding that in RR Path, I end up learning all the immuno I need to know (the HY aspects anyway). I read thru Levinson's and then the chapter on Immunopath, and I liked it better via Goljan, but I'm sure I understood it b/c of Levinson's. All the main points showed up in Goljan. Also, after going thru 1st Aid Micro, Goljan reinforces it clinically. If anything, I'd probably consider reading HY CMB, but I am not sure if it's necessary. So yeah, I'm really considering consolidating my studying to 1st Aid/MedEssentials (MedEssentials esp. for the Behavioral part), RR Path, HY CMB, and BRS Physio ... and the rest Kaplan Qbank and eventually UW.
