How do you say i was bad at it in spanish?

Answer 1

There are two ways you can say it, depending on the preposition used ("para" or "en").

In the case below, the phrase can be followed by the verb in the infinitive or by a noun (preceded by the appropriate article).

"Yo era malo para... jugar tennis / el tennis"

"Yo era malo para... las matemáticas".

The following case calls for the noun only (either preceded by an article or without it). Save

Yo era malo en...el tennis.

Yo era malo en ... matemáticas.

This case is mostly used with just the noun (usually preceded by the adequate article except when using names of study subject, i.e. historia, física, etc.
