Subjunctive doubt
On the AQA A-level grammar list.
The short version
One no flips the whole clause
Ask one question: are you vouching for the clause? Creo que viene asserts it, so the indicative stays. Put a no in front and you have withdrawn your weight, so it flips to no creo que venga. The flip works both ways too, since negar takes the subjunctive but no niega que la conoce lands back on an assertion.
No creo que venga.
That's the gist. The full article goes deeper - more examples, the edge cases, the why - and the practice below scores like a vocabulary session and earns the same XP.
