Columbia summer session admissions for undergraduates

<p>Hello everyone! I understand that NYU has a not-very-competitive admissions process to get in for the undergrad summer session, and I called Columbia University about their summer admissions and they were very vague, then transferred me to someone who basically told me that it's 'even harder to get in for summer because all they look at is GPA and nothing else'.
Really?!
Does anyone else have experience with the summer session admissions at Columbia?</p>

<p>Also, what are some other schools like NYU where it's relatively easy to get in for summer (if you have an undergraduate GPA above 3.0 but not 3.8 or 3.9).</p>
