I completely disagree with MortimerC .
Your best option is to transfer with 70 units. Often times the upper-division requirement will not get you to the minimum number of units you need to graduate.
Take for example -Economics at UCLA UCLA Department of Economics
Economics 1 --Econ 1 should be complete
Economics 2--Econ 2 should be complete
Economics 41--Stats you have to take at UCLA
Math 31A-Calc 1 should be complete
Math 31B-Calc 2 should be complete
Economics 11 -Micro Theory take at UCLA
Any L&S Writing II Requirement - English 2 should be complete
Economics Elective #1
Economics Elective #2
Economics Elective #3
Economics Elective #4
Economics Elective #5
Economics Elective #6
Economics Elective #7
So that leaves 11 classes for the major at UCLA which is 44 units only
To graduate you need 180 units
so if you transfer with 60 you start at 90 units
90+44=134 which leaves you 46 units short
However if you transfer with 70 max units you looking at 105 units transfered in +44 mandatory
you end up at 149 so you only need 31 .
At 105 you only need 75 to graduate so you can take a much easier pace you assume 2 years to graduate so basically 6 quarters.
you need ~ 12.5 units per semester to graduate which is a very easy pace. You can basically take 1 summer class in 2 years and graduate taking the minimum units needed to graduate. This also allows you to double major MUCH easier which is believe is just taking 1 extra class per semester to push it to 16 units
however if you transfer with only 60 semester units you need 90 quarter units to graduate
which means you need 15 units per semester to graduate so you definitely need summer classes or 16 units a semester. Double majoring is much tougher which means ~ 20 units a semester.
p.s Unit cap at UCLA is 216 units
which is more than enough for any double major
