Short bursts, fast feedback, and a report that tells you where to go next. Drill the Spanish structures that carry the grammar-control score on all eight constructed responses, then run speed rounds on the acquisition theory the 613 asks about and the PACT never does.
Pick a structure from the rail and the video swaps in place. Playback keeps running while you work every module below — pin it and the player follows you down the page.
Everything below filters to your picks — drills, question bank, and report. Your selections stay put when you come back.
Three interactions on rotation: sort into buckets, drop the right form into the gap, tap the one word that breaks. Missed items come back around later in the session.
Exam-style selected response at the difficulty the 613 rewards: longer context, embedded clauses, and choices that turn on register. The queue leans toward whatever you have been missing.
Teoría Turbo is open now. The rest are in the build queue — tell us which one to finish first.
Accuracy by structure, weakest first, with the three moves that pay off fastest.
Tell us your test date and where the 613 is giving you trouble, and we will map the weeks between now and then.
