UCSC TAG Policy? Someone PLEASE help!

I attended the University of Nevada Reno last year and received two F’s. One in Trigonometry and the other in Community Health Science. I am soon to be attending De Anza in a couple of weeks and I am hoping to transfer to UCSC as an economics major. I looked into UCSC’s TAG requirements http://admissions.ucsc.edu/publications/tag-2017-flyer-final.pdf and noticed that they didn’t state anything about needing to have a 2.0 © in all UC-Transferable course work, but instead showed a Screening criteria for the Transfer applicants. As for my major (Economics) they only required three courses to receive at least a C in and 2.80 Total between the three combined courses. These courses are Econ 1,2, and Calc 1. http://admissions.ucsc.edu/apply/transfer-students/major-prep.html#econ Will I be okay as long as I get the grades required for the screening criteria with an overall combined UC GPA of 3.0 by the time I submit TAG?

My 2nd question is:
I noticed that I will be completing my IGETC and required prerequisites by the time next November is around (next application cycle for UCSC transfer applicants) and would have basically a whole gap year/half year without having to take any classes. Would this affect my application? I will be taking about only one class per quarter from that point just to boost GPA, but that is practically it. Along with that I will be focused in finding an internship, job shadowing, and volunteering. Thank you for your guys time and help!
