another 1st year P & Ser here. just wanted to add my voice about the technology thing, because i got the same impression on my interview here last year (that they were nonexistent). i was pleased to find when i came here that my impression was way off.
they're actually QUITE good. all the lectures are recorded, and some pertinent ones (such as neuroanatomy) are videotaped. there are some phenomenal online atlases for histology, anatomy and neuroanatomy designed by our instructors here and made specifically for columbia students that the whole class relies on. old exams are posted for us to use to study. in our physiology course, not only are the lectures recorded, but the lecturers will also sit down and record a 20 minute, truncated lecture timed with the slides going over the most important information from each slide.
in addition, before every exam block, the 2nd years hold study sessions for the 1st years to review all the lectures and provide us with an indispensable study packet to help guide our pre-exam study efforts. it's really remarkable.
our physiology instructor has also designed his own online simulators for renal, cardio, and pulmonary, which i have secretly provided to students at other med schools because they are so useful. he also will frequently host "online office hours" from his home where he'll go over the simulators via online conferencing with us and answer any questions we may have. we also do that interactive clicky thing during many lectures to keep us active and awake.
also -- there is now wireless in bard.
so yeah, don't let the seeming lack of technology spook you. as pjl said, there is more than enough provided to allow us to succeed. and if you take advantage of them you will have no problem succeeding.
