Tu estudas muito para que passes no exame.

Tu is the informal singular word for you in European Portuguese. It is very common in Portugal when speaking to friends, family, children, and many people you know well.

Because the sentence uses tu, the verbs also have to be in the 2nd person singular:

• tu estudas
• tu passes

If you used você, the verb forms would be different:

• você estuda
• você passe only in a subjunctive structure, but everyday phrasing would usually change too

In Portugal, você exists, but it can sound distant, marked, or region-dependent, so learners of European Portuguese often hear tu a lot.

You can leave it out.

Portuguese often drops subject pronouns because the verb ending already shows who the subject is. So this is also natural:

Estudas muito para que passes no exame.

Including tu can add:

• emphasis
• contrast
• clarity

For example, if you want to stress that you, not someone else, study a lot, keeping tu makes sense.

Estudas is the present indicative form of estudar for tu.

It is used because the main clause is presented as a normal, real action or habit:

• tu estudas

So the sentence starts with an ordinary statement in the present tense. The special part comes later, after para que, where Portuguese switches to the subjunctive.

Para que introduces a purpose clause. It means something like:

• so that
• in order that

So the structure is:

• main action: Tu estudas muito
• purpose: para que passes no exame

In other words, the second part gives the goal of the studying.

No, not in standard Portuguese.

If you use a finite verb after para, you normally need que:

• para que passes

Without que, Portuguese normally wants an infinitive instead:

• para passar no exame
• para passares no exame

So:

• para que + subjunctive
• para + infinitive

are the normal patterns.

Because para que requires the subjunctive.

• passas = present indicative
• passes = present subjunctive

After para que, Portuguese uses the subjunctive because the result is a goal, intention, or desired outcome, not a simple stated fact.

So:

• Tu passas no exame = you pass the exam
• para que passes no exame = so that you may pass the exam / so that you pass the exam

Passes is the present subjunctive, 2nd person singular, of passar.

A quick mini-table:

• eu passe
• tu passes
• ele/ela passe
• nós passemos
• vós passeis
• eles/elas passem

In this sentence, passes matches tu.

It is grammatical, but in European Portuguese many speakers would often prefer an infinitive structure here, especially because the subject is the same person in both parts of the sentence.

A very natural alternative is:

Tu estudas muito para passares no exame.

That often sounds smoother in European Portuguese when:

• the subject of both verbs is the same
• the second clause expresses purpose

So para que passes is correct, but para passares may sound more idiomatic in many everyday contexts.

Because Portuguese has a personal infinitive, which can show who the subject is.

So after para, European Portuguese very often likes:

• para passares = for you to pass / in order for you to pass

Here, passares agrees with tu.

You may also hear para passar, especially in less marked or more general phrasing, but para passares is very natural in Portugal because it clearly matches the subject.

No is a contraction of:

• em + o = no

So no exame literally means in the exam, but with passar, Portuguese uses this structure idiomatically to mean pass the exam.

This is something you usually just learn as part of the expression:

• passar no exame

If the exam were nonspecific, you might also see:

• num exame = em um exame

Here muito is an adverb meaning a lot. It modifies the verb estudas:

• estudas muito = study a lot

This position is the normal one in Portuguese. So:

• Tu estudas muito... is natural

It is not an adjective here. It does not describe a noun; it describes how much you study.

It works in both European and Brazilian Portuguese, but it feels especially natural as a European Portuguese example because of tu.

A Brazilian speaker would often be more likely in everyday speech to say something like:

• Você estuda muito para passar na prova.
• Você estuda muito para passar no exame.

Also, European Portuguese is especially comfortable with the alternative:

• para passares

So the sentence is not exclusive to Portugal, but its style fits European Portuguese very well.
