JAG and AG units 1-10 doesn’t cover 1/2/3 person, singular/plural, verb tenses and participles. It focuses on parts of speech, parsing, and diagramming. JAG Mechanics does teach some of those things, we used it and learned a great deal though it’s not perfect.
If your student is ready, you could just do AG season 1 (exact same content as JAG, but a bit longer sentences), then next year just use the review and reinforcement book. That’s one exercise every other week. Then start with season 2 of AG. When we return to season 2 next year, we will do only 6-7 parsing/diagramming exercises per unit. 10 felt like overkill.
