Simulate the real thing. Or simulate nothing.
If your practice doesn't replicate the real exam — the exact task types, the exact timing, the exact marking criteria — you are not preparing for Cambridge. You are rehearsing for a different test than the one you'll sit.
Every session on Upslang is built to the same structure as the official exam: same format, same question types, same time pressure, same scoring framework. Not inspired by it. The same shape.
A simulation is only useful when it is accurate. Anything less is wishful thinking dressed up as revision.
