Nakaupo kaming tahimik habang ibinibigay ng guro ang marka namin sa pagsusulit.

Nakaupo describes a state or condition: being seated or sitting.

• nakaupo = sitting / seated
• umupo = to sit down
• naupo = sat down / ended up sitting

So in this sentence, the idea is not that we sat down at that moment, but that we were already sitting while something else was happening.

Kaming is kami plus the linker -ng.

The linker connects kami to the following descriptive word tahimik:

• kami = we
• kaming tahimik = we, quiet / we who were quiet

This is a very common pattern in Filipino when a pronoun is linked to a modifier.

No. Kami is exclusive we.

That means it includes the speaker and some other people, but not the listener.

If the listener were included, Filipino would normally use tayo instead.

So kaming tahimik means we were quiet, but not necessarily including the person being addressed.

It is basically an adjective, but in this sentence it works like English quietly.

So:

• Nakaupo kaming tahimik literally feels like We were seated quiet
• Natural English becomes We sat quietly or We were sitting quietly

This is normal in Filipino: words that are adjectives in form often cover adverb-like meanings too, depending on the structure.

Habang means while.

It connects two actions or situations happening at the same time:

• Nakaupo kaming tahimik = we were sitting quietly
• habang ibinibigay... = while ... was being given / while ... was giving ...

So the sentence shows simultaneous action.

Ibinibigay is the imperfective form of ibigay.

In this sentence, it shows an ongoing action in the past context of the sentence: the teacher was in the process of giving out the grades.

A useful comparison:

• ibinigay = gave / was given
• ibinibigay = is giving / was giving / is being given
• ibibigay = will give / will be given

Compared with nagbibigay, ibinibigay puts the focus on the thing being given rather than the giver.

Here, the thing in focus is ang marka namin.

Because the verb form ibinibigay is a form where the thing being given is the grammatical focus.

In that pattern:

• the focused item gets ang
• the doer/actor gets ng

So:

• ang marka namin = the grades are the focused item
• ng guro = by the teacher

This is why the teacher is marked with ng, not ang.

Because ang marks the noun phrase that the verb is focused on.

Since ibinibigay focuses on what is being given, the grades appear as:

• ang marka namin

This means something like our grade(s) as the item being handed out or announced.

So the structure is:

• ibinibigay = was giving
• ng guro = by the teacher
• ang marka namin = our grades

Both are possible, but they are used a little differently.

• marka namin
• aming marka

In many everyday sentences, noun + namin is very natural and common.

So ang marka namin is a normal way to say our grade(s).

A rough difference:

• aming marka can sound a bit more formal or emphatic
• marka namin is very natural in ordinary speech

Sa pagsusulit tells you what the grades are for or in relation to.

Here it means something like:

• on the exam
• for the test
• in the test

Pagsusulit is a noun meaning exam or test.

So ang marka namin sa pagsusulit means our grade(s) on the exam.

Good question. Marka is singular in form, but the sentence can still be understood naturally.

Depending on context, ang marka namin can mean:

• our grade, collectively understood
• each of our grades, depending on the situation

If you want to make the plural more explicit, you could say:

• ang mga marka namin sa pagsusulit

That would clearly mean our grades.

So the original sentence is still acceptable; it is just a little less explicitly plural.

Yes, that is possible.

For example:

• Nakaupo kaming tahimik
• Tahimik kaming nakaupo

Both are understandable and natural, but the emphasis shifts slightly.

• Nakaupo kaming tahimik highlights the seated state first
• Tahimik kaming nakaupo highlights being quiet first

Filipino word order is often flexible, especially when the meaning is already clear from markers and context.
