Transfer or First year? UC

Once you have taken college courses after the summer after high school graduation, UC wants you to take the transfer pathway. This means that you need to take enough college course work so that you will have at least 60 semester units by the time you transfer. Plan to take about two years worth of courses at community college before transferring to UC (you will apply during the year you will complete the 60 semester units with needed course requirements).
