Hope you get admitted. Take summer school there then. There was a student who graduated after I did who bought airsoft guns to engrave on. He worked in the tool room there and when not distributing equipment or material to students, tapped away. He had an advantage in that he had an art degree and was familiar with roccoco. He'd draw the initial design and then free handed the detail. When finished, he sold the airsoft for a profit and helped pay for school.
I'm still pestering the school to have one of the engraving instructors (Michael Pierson or Joe Rundell) teach roccoco drawing as part of the required "drawing" class for the fine arts certificate. Besides and Associate in Science degree in gunsmithing, TSJC students can earn a gunsmithing certificate for those who don't complete the A. S. degree requirements. A couple of my classmates went this route since they didn't take English, math (you have to contact TSCJ) or other courses the A. S. degree requires. Knock those out cheaper at San Francisco City College while you're there. The other certification they grant are Gunsmithing Technician Certificate, NRA Instructor certification and, Fine Arts Certificate. A lot of veterans go for all five and it's given a boost to the stock carving (relief carving ala long rifle decoration), engraving, advanced engraving, alternative metal finishes classes.
If you're planning to attend TSJC, enroll in the NRA summer school there. Might I suggest Tig Welding for gunsmiths and bluing. This will reduce your workload in the first and second semester. For bluing you should know already how to disassemble and reassemble a firearm. It doesn't need to be anything fancy and don't do AR-15s (aluminium can't be placed into hot salt baths since the salts will dissolve them). See if you can find an old beater single shot 22 cheap.
I'd also take Machine Shop I & II, especially if Keith Gipson (the dean) is teaching. It won't count towards your degree, but you'll have the advantage of already knowing how to operate a lathe and milling machine.
Also check out the school library. Most students don't but there's a treasure trove of information there.
