How many subject tests?

<p>From what I've seen, most colleges only ask for two of your scores. However, everyone around me is taking 3 or 4 tests, and I'm baffled as to why. Does it give you an advantage to take more??? Or can I just take two and be content in my little corner of the universe? I want to apply to the top schools, and I need all the help i can get.</p>

<p>i took three b/c at the time when i was planning all this, most schools still wanted 3. i later found out that they changed their plan to 2. however, i still needed to take the last one b/c they required that subject, Math Level 2. thus, that is how i ended up taking three. no need to take more than the suggested, waste of time.</p>
