Pre-MBA or CC?

Hi,

I am an international student located in SF bay area. I already have a degree in Law from Europe but I'd like to get a masters in Finance/Economics in the US. I can't apply to MBAs as I do not have enough work experience. I want to do it later in my career.
Firstly, I want to get fundamental courses(like calculus, statistics and microeconomics) completed so I can actually make it to a top graduate school. I am considering completing them either at a CC or in a Pre-MBA certificate program such as UCLA Pre-MBA. I am quite close to De Anza and Foothill which are accepted as top CCs, I can take those courses in one of them and study for GMAT in the meantime. Second option is to relocate to LA and complete the Pre-MBA at UCLA which consist of:
Principles of Financial Accounting
Applying Economics to Business Decisions
Mathematical Solutions for Businesses
Marketing Principles and Practice
Applied Managerial Finance
Strategic Thinking: Tools, Processes, and Cases

Which option would you recommend in order to get an admission from a top school just in terms of education background?

Thanks!
