question on "pre-xxx" schools

there are pre-law,pre-med,pre-pharm,pre-business etc etc…
so my question is… are these “pre-xxx” courses the name of an actual course that is completely dedicated to the “xxx”? And in order to apply to these med school or pharm school you need these required courses right? Does every school offer these required courses? Also does it matter what you major in?

<p>pre -XXX is just a title a student is like I will be pre-med at UCI so I will be taking pre med courses such as chem physics bio calc pre-med is not a specific major pre-med is just a title part of being pre-med is just taking those pre-med courses pre-med courses are just a few required courses to help get into med school</p>

<p>so do everyone school offer these pre-xxx courses? or are there certain schools that offer certain pre-xxx s</p>
