Not every candidate can clear four consecutive weeks. Ships do not stop, leave gets moved, and exam dates arrive at awkward times. This route exists for that situation.
The preparation focus is the same as the standard Masters oral course — seamanship, magnetic compass, shipmaster's business and law, and command-level scenario work — delivered remotely and arranged around what you can realistically commit to.
Because it is arranged individually, the timetable and fee are confirmed when you enquire rather than published as a fixed package. It is preparation for the MCA oral examination, which the MCA conducts separately.
