I'm a little confused. You've already got a test date and you haven't taken your required courses yet?
You may want to check this out first. It's right from the DRE official website:
Requirements to Apply for a Real Estate Salesperson License
To obtain a real estate salesperson license, you must first qualify for and pass a written examination. Those who pass the examination are provided a license application which must be submitted to and approved by the DRE.
This license is required of individuals who conduct licensed real estate activities as described in the Real Estate Law under the supervision of a licensed broker. A license may also be obtained by a person who does not immediately intend to be employed by a broker. However, a salesperson without an employing broker may not perform acts requiring a real estate license.
Successful completion of three college-level courses is required to qualify for a real estate salesperson examination:
Real Estate Principles, and
Real Estate Practice, and
One course from the following list:
Real Estate Appraisal
Real Estate Finance
Real Estate Economics
Legal Aspects of Real Estate
Real Estate Office Administration
Mortgage Loan Brokering and Lending
Computer Applications in Real Estate
Common Interest Developments
If you haven't completed these courses you won't be able to even take the test. You really should contact Laura King at Allied RE school in Irvine ASAP. She can walk you through the steps you need to go through. I'd definitely be thinking about rescheduling the test if you have taken the prerequisite courses yet. Good luck.
