I did not like my psych clinical until the very end.  To be honest I was scared.  I was in the acute care section a couple of times and was very nervous to talk to the patients.  Then the 2nd to last clinical I was in a group home for kids and really enjoyed it.  And the last psych clinical I was in a general psych unit and got over my fear and spent a little time talking to the patients.  As far as studying for both classes.  For med surg well the 2nd and 3rd med surg classes I just had to break out the book and read it.  For psych I used my NCLEX book to help me study for my test. 

Do they still have those review cards for the NCLEX?  After I graduated, my friends and I used to each grab a handful and take turns asking the questions.  It was a great way to study.  As I recall they came in a box with all the subject separated.  We mixed them all up but you could just look at the Psych ones if they still make them.  They came in a box like recipe cards.

Good Luck!
