Here's his description of the course:
Suitable for beginners, this unique course teaches Latin slowly from the ground up, using spoken Latin, while keeping a firm grip on grammar. The first 2 lessons have some English. The rest are only in Latin. You will need to study the course in sequence, as each lesson follows the preceding one in a progressive order.
As the course is taught totally in Latin, you need no other language.
The course will teach you to read and write and speak Latin.
Dictation and writing exercises will be introduced later on in the course.
