you send immunications to the Health Services Office. You can go there in person at hunter North room 307. There is hardly anyone in there and they usually have 2-3 workers there to help out.
Also you need to need sign a waiver for menegitis I believe. you need to acknowledge you are aware of how it is a health threat and you can get either get immunized for it or just sign an acknowledgement.
They need both your records and the menegitis form to clear holds.

I had zero problems with registering,financial aid, and transferring into Hunter. I think it is help for the financial aid if you have all of your documents and you visit the office in the semester you plan to attend preferably after the first few weeks. I did this and there was hardly a line of more than 8 people, short wait, and the people there were helpful and knowledgeable.
One thing to look out for is that you stay on top of them for evaluating your transcript ASAP. Then look it over and make sure ALL of your classes transfered and if not talk to someone in the admissions office. Having your old college catalog or a printout from their website helps.
another is to look out for getting a hold placed on you when applying to classes. You may get credit for your gen chem classes but on your transcript they do not mark it as an equivalent so it is possible you will have to take your old college catalog or website printouts showing equivalency to the chem dept so that there is no academic hold.
make sure your transcript credits you for physics I as well.
I had to do this for orgo.
don't know about the rest. The web site does not show when registration will start for sping 2005 as of now. good luck.
