Congratulations!!! I've actually started looking over my old SLP-Assistant textbooks. Definitely start memorizing your anatomy especially with the neck and head portions along with the brain. Gain understanding of the basic functions. That will alleviate a lot of stress for later. I've also been brushing up on basic communication lingo such as receptive, expressive, morphemes, phonemes, articulators, etc. I hope this helps =P
ps. ooo you can also start memorizing the phonetic (IPA).
