I heard you had to get >9.5 average on a full course load to make it. I was just wondering if summer courses were taken into consideration? I dropped a course first term and I was not allowed to overload second term to make up the lost credit. I am planning to take that make-up course in the summer. Does not completing 30 credits for Fall/Winter-Winter/Spring term for 2015-2016 mean I can't make the list even if I am able to get a 9.5+ average?

It says in the undergraduate calendar that the review period will be when you have completed a minimum of 30 units since your last review period. So if your last review period was April 2015 and you haven't finished 30 units by April 2016 then your summer courses should let you get deans' list.

Just to add to the previous post, if for example you HAD completed 30 units in Sept-April, then you'd be reviewed then, and not after the summer session, so your summer courses would count in the next review you get (which should be the following April).

And just a technical note - there is no "fall-winter" and "winter-spring" term, and using that wording will only confuse you if you're looking in the course calendar or on the Mac website. The fall/winter session runs Sept-April, and consists of the Fall term (Sept-Dec) and Winter term (Jan-Apr). The spring/summer session runs May-Aug, and includes a Spring term and a Summer term.
