Go for it! Trish told me that they will have better Fall/Spring enrollment and that it's wise to enroll early! All the information you'll need can be found on the Adobe Acrobat file I've uploaded to the link above.
Thanks for posting this, Carissa. Our family has enjoyed the UNM music prep classes for almost 7 years now.
Kim, you can also call or email them to mail you a registration form. From their web site:
FOR REGISTRATION FORM AND REGISTRATION, CALL THE UNM MUSIC PREP SCHOOL AT 505/277-8816 or send e-mail to email@example.com. Please note: Classes have limited enrollment; therefore, please register as early as possible.
