The basic entrance requierments are stated below

"Have a bachelor's (or equivalent) degree

or be in the final year of your bachelor's degree program at the time of registration

or have four years of qualified, professional work experience

or have a combination of work and college experience that totals at least four years (Note: Summer, part-time, and internship positions do not qualify)

If you initially enroll/register as a final year undergraduate student with a degree in progress, you may not register for the Level II exam until you have earned your degree, or obtained work experience that meets the program’s entrance requirements. At the time your degree is awarded, you may update your account education information to certify that your degree has been received."

So for your case, you need prove you have 4 year working experience (irregard if the 4 year working experience is financial or professional related) together with your diploma.
