Best advice is to meet with the on-site Transfer counselor at your CC as soon as you can, hopefully before selecting classes. They will be able to help you navigate the courses and timing you’ll need to transfer at the two-year mark.
They can help you to decided - based on your potential major - if you want to follow the IGETC or a major-specific pathway.
Note that there are a few requirements (in the Communication and Critical Thinking categories) that the CSU’s have and the UC’s don’t. Be sure you have your end goal in mind (UC, CSU or private) as you plot your course.
Good luck
