The Independent Contractor Agreements that I have seen, and been a Party to, have been on-going and did not have a specific Termination Date; but they usually contain clauses regarding cancellation by either or both of the Parties.
Once you have business on the books, in the form of Contracts with Sellers and Buyers, your business will be on-going, as a function of their Contracts running their course and being constantly replaced by others. Consequently, there won't ever be a convenient end date for your Contract with the Broker.
After you've completed your classes, and actually passed the examination, you'll be in a much better position to participate in negotiating such a Contract. Plus, the Broker will know that you've actually made the commitment of completing these initial steps, and should take you more seriously.
Many people take an interest in becoming a licensee, but a substantial percentage never get to the point of becoming qualified for licensure.
