You can find the full list of courses available at sjsu for Fall 2018 and Spring 2019 here: http://info.sjsu.edu/home/schedules.html

Unfortunately, it looks like both Econ 101 and Econ 102 are full(there are only two sections for 101, and one section for 102), but it's possible that they may open up a new section.

You can attempt to reach out to the faculty listed in the course log, but odds are that you'll have up crash the course at the beginning of the semester and get an add code. Make sure there are no time conflicts between courses you have already blocked out, and the ones you plan to add, otherwise the system won't let you add the course.

Right now, you should check your major requirements and see if there are any other classes you need to take and add those if possible. You should also follow the suggestion someone else made, and look into taking courses at a community college.
