The C1 Level-Up Plan
Eight weeks from strong B2 to solid C1.
C1 is flexible, accurate English: you catch implicit meaning, you choose your register on purpose, and your sentences carry emphasis exactly where you want it. Nothing here is new basic grammar. It is range and control: inversion, cleft sentences, participle clauses, hedging, and a vocabulary that includes the word everybody almost knows. This plan is the guided part of that climb.
The honest math: moving up one CEFR level takes roughly 150 to 250 guided hours, and the B2 to C1 step is the widest of them all. This plan, at about an hour a day, five days a week, gives you around 40 of the most targeted hours there are. If you are at the top of B2, that is enough to cross. If you are mid-B2, finish this block, retest, and run it again with fresh material. C1 is a marathon level; we just make sure every hour counts.
