بعد از کلاس از استادم درباره امتحان سوال کردم.

Because standard Persian word order is usually Subject – (other parts) – Verb.

So in this sentence, the verb سوال کردم comes at the end, which is very normal in Farsi.

A rough breakdown is:

• بعد از کلاس = after class
• از استادم = from my professor/teacher
• درباره امتحان = about the exam
• سوال کردم = I asked / I asked a question

This “verb-last” pattern is one of the biggest differences from English.

Literally, بعد از کلاس means after class or after the class.

• بعد = after
• از = from / after (in this expression)
• کلاس = class

In Persian, بعد از is a fixed expression meaning after.
So you should learn بعد از as a unit.

Examples:

• بعد از کار = after work
• بعد از غذا = after food / after the meal
• بعد از امتحان = after the exam

In Persian, when you ask someone something, the person you ask is often marked with از.

So:

• از استادم سوال کردم = I asked my professor

This is different from English, where we say I asked my professor without a preposition.
Persian often uses از in this kind of structure, almost like from.

So the logic is closer to:

• I asked from my professor about the exam

Even though that sounds unnatural in English, it matches the Persian structure well.

استادم means my professor or my teacher.

Breakdown:

• استاد = professor / teacher / instructor
• -م = my

So:

• استاد = professor
• استادم = my professor

This -م is a possessive ending attached directly to the noun.

Other examples:

• کتابم = my book
• دوستم = my friend
• کلاسم = my class

Because they do two different jobs:

• از استادم tells you who I asked
• درباره امتحان tells you what topic I asked about

So the sentence separates:

1. the person asked
2. the subject asked about

This is very common in Persian.

Pattern:

• از [person] درباره [topic] سوال کردم
• I asked [person] about [topic]

Example:

• از دوستم درباره فیلم سوال کردم
  = I asked my friend about the movie.

Because امتحان here is not the direct object of the verb. It is the object of the preposition درباره.

• درباره = about / regarding
• امتحان = exam

So درباره امتحان means about the exam.

The marker را is normally used for a direct object, but here امتحان comes after a preposition, so را is not used.

Compare:

• امتحان را دیدم = I saw the exam
  → امتحان is a direct object, so را can appear.

But:

• درباره امتحان سوال کردم = I asked about the exam
  → امتحان belongs to درباره, so no را.

Because Persian often uses compound verbs: a noun + a light verb.

Here:

• سوال = question
• کردم = I did

Together, سوال کردم means I asked or more literally I asked a question.

This is a very common pattern in Persian.

Other examples:

• کار کردم = I worked
• فکر کردم = I thought
• صحبت کردم = I spoke

So even though کردم literally means I did, in combination with certain nouns it creates a full verb meaning.

Yes. پرسیدم also means I asked.

So you could say:

• بعد از کلاس از استادم درباره امتحان پرسیدم.

That is also correct and natural.

Very roughly:

• سوال کردن = to ask / to ask a question
• پرسیدن = to ask

In many situations, they are interchangeable.
پرسیدن is a simple verb, while سوال کردن is a compound verb.

Learners should understand both.

Yes, they are the same word: question.

You may see it written in two ways:

• سوال
• سؤال

In modern everyday writing, سوال is very common.
The spelling سؤال is a bit more traditional or formal-looking.

For a learner, the important thing is that both represent the same word and are pronounced essentially the same in normal speech.

Yes. The subject I is understood from the verb کردم.

• کردم = I did
• so سوال کردم = I asked

Persian often drops subject pronouns when the verb ending already makes the subject clear.

So:

• من سوال کردم = I asked
• سوال کردم = I asked

Both are possible, but leaving out من is very normal.

The sentence can be rearranged somewhat, but the verb usually stays at the end.

The given sentence is very natural:

• بعد از کلاس از استادم درباره امتحان سوال کردم.

You could also hear:

• از استادم بعد از کلاس درباره امتحان سوال کردم.

This is still understandable, but the original version sounds smoother and more neutral.

For learners, a good rule is:

• put time expressions early if you want
• keep the main verb at the end

So the original sentence is an excellent model.

A natural pronunciation would be close to:

ba’d az-e kelâs az ostâdam darbâre-ye emtehân soal kardam

A few helpful notes:

• بعد از is often pronounced smoothly together.
• استادم sounds like ostâdam.
• درباره is often followed by a linking sound before the next word:
  درباره‌ی امتحان = darbâre-ye emtehân
• امتحان is usually pronounced emtehân in everyday speech.

So if you say it smoothly, it will sound connected rather than word-by-word.

It can mean several related things depending on context:

• professor
• teacher
• instructor
• sometimes even master/expert

In a university context, استادم usually means my professor or my instructor.
So in this sentence, my professor is probably the best translation, but my teacher may also be possible depending on the situation.
