الطالبة رسبت اول السنة، وبعدها رفعت علامتها وصار معدلها احسن.

Because الطالبة is the feminine form of student. The sentence is about a female student, so Arabic uses the feminine noun.

• طالب = male student
• طالبة = female student

The ending -ة is a very common feminine marker.

That -ت marks the past tense, feminine singular form of the verb in this sentence.

Since the subject is الطالبة (a female student), the verbs that refer to her are feminine singular:

• رسبت = she failed
• رفعت = she raised / improved

This is very normal in both Levantine and Standard Arabic.

In Levantine Arabic, subject + verb order is very common, especially in everyday speech.

So:

• الطالبة رسبت = the student failed

is very natural in conversation.

You could also hear رسبت الطالبة, but that sounds more formal or more like written Arabic. Colloquial Levantine often prefers starting with the topic/person first.

رسبت comes from رسب and means she failed.

Depending on context, this verb can mean failing:

• an exam
• a subject/class
• a school year

In this sentence, the exact thing she failed is understood from context. The learner should know that رسب is the normal verb for to fail academically.

اول السنة means the beginning of the year or early in the year. In a school context, it usually means the beginning of the school year.

This is a type of phrase called an iḍāfa (construct phrase):

• اول = first / beginning
• السنة = the year

In Arabic, the first word in this structure often does not take ال, even though the whole phrase is definite because the second word is definite.

So اول السنة means literally something like the beginning of the year.

Because this is very common in informal Arabic writing, especially in dialect.

So:

• اول = أول
• احسن = أحسن

When people write Levantine casually in messages, posts, or subtitles, they often leave out hamzas. The meaning does not change.

وبعدها means and after that or afterwards.

It breaks down like this:

• و = and
• بعد = after
• ها = it / that / her, depending on context

Here, ها does not really mean her in a personal sense. It refers to the previous situation or time period, so the whole phrase means after that.

Literally, it means she raised her grade/mark.

This is a very natural Arabic way to say that someone improved their grade.

Breakdown:

• رفعت = she raised
• علامتها = her grade / her mark

So Arabic uses a verb like raise where English might more naturally say improve.

علامتها has three parts:

• علامة = grade / mark
• the ـة changes shape when a suffix is added
• ها = her

So علامتها means her grade or her mark.

This suffix system is very important in Arabic. Instead of saying a separate word for her, Arabic often attaches it directly to the noun.

They are related, but they are not the same thing.

• علامتها = her grade / mark
  
  • often one grade, or a grade in a subject
• معدلها = her average
  
  • like her overall average or GPA

So the sentence says that she improved a grade, and as a result, her average became better.

Because the subject of صار is معدلها (her average), not الطالبة.

• معدل is grammatically masculine
• so the verb is صار = it became

If the subject were the female student herself, then you would expect صارت.

So the grammar is:

• صار معدلها احسن = her average became better

The verb agrees with معدل, not with the student.

Here صار means became.

This is one of the most common uses of صار in Levantine:

• صار كبير = he became big / older
• صار منيح = it became good
• صار معدلها احسن = her average became better

In everyday Levantine, صار is extremely common for talking about a change of state.

Yes. Here احسن means better.

So:

• منيح = good
• احسن = better

In colloquial Arabic, احسن can sometimes mean better and sometimes best, depending on context. In this sentence, it clearly means better.

Because Arabic, especially spoken Arabic, often connects events with و (and) even where English might split them more sharply.

So this kind of chain is very natural:

• ... رسبت
• وبعدها ...
• وصار ...

It gives the sentence a smooth narrative flow: one event happened, then the next, then the result.
