Anyone with Finance Diploma?

Ive just completed the first 3 out of 8 subjects at diploma level. I know there are a few people here who have gone all the way. Can you offer any advice about which subjects are easier and more useful to a trader.

Done:

301 - Understanding Finance Industry
302 - Business and Finance Practice
310 - Financial Planning and Wealth creation

Want to do:

401 - Financial markets economics
405 - Stock market and products
502 - Understanding derivatives

Then theres:

515 - risk management and insurance products (compulsary....urgh!)
507 - managed funds industry
501 - managing and marketing financial products
500 - analysing company performance

Im leaning towards 501, cos it sounds like the least boring one. But open to suggestions......

Am I crazy to do these 5 subjects in one semester?
