Félicitations pour ton score !

In French, félicitations is normally used in the plural to mean congratulations. That is just the standard expression.

So:

• Félicitations ! = Congratulations!

A singular form, félicitation, exists, but it is much less common in everyday speech and usually not what you want here.

Here, pour means something like for in English.

So:

• Félicitations pour ton score ! = Congratulations on your score!

French often uses pour after félicitations to say what the congratulations are about:

• Félicitations pour ton examen !
• Félicitations pour ta réussite !

English can say congratulations on something, but French commonly says félicitations pour something.

Because score is a masculine noun in French.

That means:

• ton score = your score
• not ta score

French possessive adjectives must agree with the noun possessed, not with the person who owns it.

So:

• ton score because score is masculine
• ta note because note is feminine
• tes résultats because résultats is plural

Ton is the informal singular your, used when speaking to:

• one friend
• a child
• someone you know well
• someone you would address with tu

Votre is used when:

• speaking politely to one person
• speaking to more than one person

So you could also say:

• Félicitations pour votre score !

That would be more formal or plural, depending on context.

Yes, absolutely. That changes the nuance a little.

• ton score refers to one specific score
• tes résultats refers more broadly to results, performance, or outcomes

For example:

• Félicitations pour ton score ! = congratulations on that specific score
• Félicitations pour tes résultats ! = congratulations on your results overall

Both are natural, but they are not exactly the same.

It is a borrowed word from English, but it is completely normal in French. People use score especially for:

• games
• sports
• tests
• competitions
• app results

Depending on context, French might also use other words such as:

• note = grade/mark
• résultat = result
• points = points

So if this is about an exam, note might sometimes sound more natural:

• Félicitations pour ta note !

If it is about a game or app, score is very natural.

No, but it is very common because this is an enthusiastic expression.

• Félicitations pour ton score ! sounds warm and lively
• Félicitations pour ton score. is grammatically possible, but it feels flatter

In writing, French often uses exclamation marks with expressions like:

• Bravo !
• Félicitations !
• Super !

A simple pronunciation guide would be:

fay-lee-see-ta-syon poor ton skor

A few helpful points:

• fé sounds roughly like fay
• the ending -tions sounds like syon
• pour sounds like poor, but with a more French r
• ton has a nasal vowel, so it is not exactly like English ton
• score is pronounced close to the English word, but with a French accent

You may also hear a smooth connection between words in natural speech, but this sentence is usually pronounced quite clearly.

Yes. Félicitations ! works perfectly on its own.

Adding pour ton score simply makes it more specific:

• Félicitations ! = Congratulations!
• Félicitations pour ton score ! = Congratulations on your score!

If the context is already obvious, the shorter version is very common.

Yes. Bravo pour ton score ! is also natural.

The difference is mainly in tone:

• Félicitations sounds a bit more like congratulations
• Bravo sounds a bit more like well done

Both are common and positive. In many situations, either one would work.

It is informal because of ton.

The structure itself is neutral, but the possessive adjective tells you the level of formality:

• Félicitations pour ton score ! = informal
• Félicitations pour votre score ! = formal or plural

So if you are talking to a friend, ton is good. If you are speaking to a teacher, customer, stranger, or a group, votre may be better.
