A question for teachers! What should I study next?
So here is what I've studied in the last couple of months:

Tenses
Conditionals
Irregular Verbs
Articles - Conjunctions - Capitalization - Independent & Dependent Clauses - Prepositions...

I've also been thinking to study (Direct & Indirect Speech) and (Active & Passive Voice) but I don't know if they're important! could you please say something about it?

Answer

You only have one real mistake in your question -- it should be "thinking of studying". So you could always have a go at verb complements, which are a bit random but important to know in everyday language.

Answer

How about having a go at speaking with real, live, NATIVE English speakers?

Answer

They're all important, if you want to sound any good as an English speaker.  I think your suggestions are good, as are Mona's.

Answer

Sentence connectors,  conversation practice, listening and reading comprehension.
