⚠️ Vanliga misstag
Llámame en cuanto llegas mañana.
Llámame en cuanto llegues mañana.
This is the most common mistake! When the main action is in the future or a command ('Llámame'), the verb after 'en cuanto' or 'tan pronto como' must be in the subjunctive ('llegues').
En cuanto a la película, me gustó.
This sentence is correct, but it's a different meaning! 'En cuanto a' means 'As for' or 'Regarding'.
Don't confuse 'en cuanto' (as soon as) with the separate phrase 'en cuanto a' (regarding). They are not related.
