Si repassessis una mica cada nit, aprovaries més exàmens.

It is a hypothetical / conditional sentence: it describes an imagined situation and its likely result.

The pattern here is:

• si + imperfect subjunctive
• conditional

So:

• Si repassessis... = if you reviewed / if you were to review...
• aprovaries... = you would pass...

This is very similar to English If you studied/reviewed a bit every night, you would pass more exams.

It suggests that this is not the current reality, but a possible or imagined situation.

Because after si in this kind of unreal or hypothetical condition, Catalan commonly uses the imperfect subjunctive.

So:

• repassessis is the imperfect subjunctive of repassar
• it matches the hypothetical meaning of the sentence

This is different from English, where learners often just think in terms of a past-looking form like If you studied.... In Catalan, the mood is more clearly marked.

A useful model is:

• Si tinguessis temps, vindries. = If you had time, you would come.
• Si repassessis cada nit, aprovaries més exàmens.

Because it expresses the result of the hypothetical condition.

In this sentence:

• Si repassessis... = the condition
• aprovaries... = the consequence

Aprovaries is the conditional of aprovar:

• jo aprovaria
• tu aprovaries
• ell/ella aprovaria
• nosaltres aprovaríem
• vosaltres aprovaríeu
• ells/elles aprovarien

So aprovaries means you would pass.

The subject is tu, but Catalan often leaves subject pronouns out because the verb ending already shows the person.

Here:

• repassessis = you reviewed / were to review
• aprovaries = you would pass

So tu is understood automatically.

You could say:

• Si tu repassessis una mica cada nit, aprovaries més exàmens.

But in most contexts, tu is unnecessary unless you want emphasis or contrast.

Here repassar means to review, especially in a school or study context.

So it means going over material again, for example:

• reviewing notes
• revising vocabulary
• going over what you learned in class

Depending on the variety of English, repassar is often best translated as:

• to review
• to revise (very common in British English)

So in this sentence, repassessis means if you reviewed / revised.

Una mica means a little or a bit.

So:

• repassessis una mica = reviewed a little / reviewed a bit

It softens the idea and makes the sentence sound natural: the speaker is not saying you need to study for hours, only a little every night.

You could compare:

• repassessis una mica = reviewed a bit
• repassessis molt = reviewed a lot

Yes, Catalan word order is somewhat flexible, though some orders sound more natural than others.

The original:

• Si repassessis una mica cada nit...

is very natural.

You may also hear:

• Si cada nit repassessis una mica...
• Si repassessis cada nit una mica...

All of these are understandable, but the original version sounds smooth and idiomatic.

Because més here directly modifies the noun exàmens.

So:

• aprovaries més exàmens = you would pass more exams

There is no article because we are speaking generally, not about specific exams already identified.

Compare:

• Aprovaries més exàmens. = You would pass more exams.
• Aprovaries els exàmens. = You would pass the exams.

You do sometimes get més de in Catalan, but not in this structure. Here the simple form is correct:

• més exàmens
• més llibres
• més classes

It is plural because the sentence means more exams, not just one.

Singular:

• examen

Plural:

• exàmens

The written accent in exàmens shows the stress:

• e-XA-mens

That open à tells you the stressed syllable is the middle one.

Yes. In Catalan, aprovar is the normal verb for to pass an exam, subject, or test.

Examples:

• He aprovat l’examen. = I passed the exam.
• No ha aprovat matemàtiques. = He/She didn’t pass maths.
• Aprovaries més exàmens. = You would pass more exams.

This is different from English, where pass is a very common everyday verb in this context. In Catalan, aprovar is the standard choice.

Yes, but the meaning changes.

Compare:

• Si repassessis una mica cada nit, aprovaries més exàmens.
  = hypothetical / less real / advice-like
  If you reviewed a bit every night, you would pass more exams.

• Si repasses una mica cada nit, aprovaràs més exàmens.
  = more direct, more real, more like a real future possibility
  If you review a bit every night, you will pass more exams.

So the original sentence sounds more like:

• advice
• a suggestion
• a comment about an unreal or not-yet-true situation

Because of the verb endings.

• repassessis = tu
• aprovaries = tu

If it were you all (vosaltres), the forms would be different:

• Si repasséssiu una mica cada nit, aprovaríeu més exàmens.

So the sentence clearly addresses one person.

A simple pronunciation guide is:

Si repassessis una mica cada nit, aprovaries més exàmens.
see reh-puh-SEH-sees OO-nuh MEE-kuh KAH-duh neet, uh-pruh-vuh-REE-uhs mez eh-ZAH-mens

A few useful points:

• repassessis has stress on -se-
• mica is roughly MEE-kuh
• nit sounds like neet
• aprovaries has stress on -ri-
• més sounds like mez
• exàmens has stress on xà: eh-ZAH-mens
