How many subject tests do I need?

<p>Do any UCs require more than 2 subject tests? I am registered to take 3 but I am only good in Math and English based SATs. My cousin said that I only need 2 so I am definitely taking:
Math 2C
and
Literature</p>

<p>But I have a third test and I unfortunately I took all of the subjects it offered last year and have forgotten a great deal of the specifics. My third test would definitely be Math 1C.</p>

<p>Here are my top 5 colleges atm:
USC
UCLA
UCI
Whittier College (only a few blocks away from my house)
and Calstate Fullerton</p>

<p>Do any of these require a third subject test? Is taking both Math 1C and 2C a bad thing?</p>
