She’s technically correct in that all your units will be combined and “counted” for your CCC transcript, but that doesn’t mean that you are exempt from the 70 unit cutoff. The difference is that once you transfer to the UCs (or CSUs), they will take that number and cap it at 70 under the label “units earned” and the rest as “subject credit.”
See the first line of the following PDF as well as guideline #1: http://admission.universityofcalifornia.edu/counselors/files/uc-transfer-maximum-limitation-policy-chart.pdf
For example:
29 Semester units at UNR
60 Quarter units (equivalent to 40 Semester units) at De Anza Community
30 Quarter units (equivalent to 20 Semester units) at Foothill Community
29+40+20 = 89 total units/credits earned at CCC/UNR
Matriculation at the UCs will enable the cap and that 89 units earned will change to 70 credits earned and an additional 19 units as “subject credit”. All transferable courses will be counted towards your UC admissions GPA and noted on your transcript, but the courses excess of 70 units they can’t be used to meet any unit-based requirement towards graduation.
This is done so transfers who go through various major and/or campus changes prior to matriculating at the UCs have the opportunity to meet their program graduation requirements without prematurely reaching the UC unit caps.
