The full Linguistic Knowledge system in one purchase. Learn it in the Course, then rep it in the Vault.

The LK Course ($69 value): 5 video modules, 23 lessons + 3 bonus lessons, built on the 5 LK Archetypes and the 3 Dimensions (Form · Meaning · Use). Includes 5 reference cards, a note-catcher for every lesson, the Pre + Post Assessment, a Timed Mini-Practice, a Mini-Mock and your 2-Week Sprint plan.

The LK Reps Vault · Vol 1 ($49 value): 4 timed mocks, 60 fresh items in Spanish, with answer keys that sort every miss into Form, Meaning or Use.

LK has no line on your score report. It sits inside about 12 Listening and Reading items, and register is scored in every Writing and Speaking task. On my retake, my Listening + Reading went from 34 / 50 to 44 / 50. This bundle is the system behind that jump. Lifetime access.
