The classes listed on assist.org as having no articulation agreement means, that these classes are not available at your CCC and you would have to take them at SLO once you transfer. If they are on SLO’s list as required, then it would be to your best interest to find a CCC that does offer the classes but since they are on SLO’s list so you should be fine. I would still take the desired courses to give you an edge on the other applicants.
