Switch out the は for も. Where we've had a lot of sentences like マリアは学生です so far, in this case you can switch out は, which in the previous context meant "is a", to も which means "is also".

Just make repetitions 100 times, than you are in again.

Me too!

Same :/

So am i, Its so annoying !

same

This is a very good question. I also think 生徒 (せいと) should be accepted.

Although there may be a technical distinction between 学生 and 生徒 as you described, from my experience working in a Japanese junior high school, the students were referred to by either word. It's hard to pin down the difference in usage, not least because I never really paid it much attention, but they seemed interchangeable in many cases.

マリア Maria も [is] also 学生 [a] student です (statement/polite particle) マリアも学生です

When it's a question. Like if you were asking if maria is a student, you would add the "ka"

+ka is like putting a question mark at the end.

When you ask a question

When its a question

Same here. That Maria really gets around

Yes, it is acceptable, but it's very informal and sounds more like a confirmatory response to a question.

Yes, it's optional, but unless you know your way around Japanese honorifics, I'd suggest using さん for everyone except yourself.

Also, the general honorific is さん san, not ちん chin as you have written. ちん is kind of a weird, sort of creepy to some, honorific otaku tend to use for nicknames.

No, it's essentially the verb "to be"

"desu" indicates the state of being. As Jake says, you can think of it as to the verb "to be". In polite speech, you have to put it whenever is needed. In informal informal conversation it can be omitted.

-学生? -学生。

Is a perfectly legit informal conversation which, in a context where a person is directly talking to another, would basically translate to:

-(are you a) student? -(Yes, I'm a) student.

That said, it's safe enough to put "desu" whenever you would use the verb "to be" I guess.

も can't come before です (which is the implied verb (copula) in your sentence). If you're interpreting the sentence as Maria is also a student (among the many other things that she is), you could say マリアは学生でもあります (maria wa gakusei demo arimasu).

も is the particle used to indicate the concept of also.

マリア 学生 です。

Mary is a student.

わたしも 学生 です。

I am also a student.

Maria san mo gakusei desu ka? Would be what you want.

I think that's only "Is Maria a student?" You need to add "mo" (also) after the person (Maria) to make it "Is Maria ALSO a student".

マリアさんも学生ですか？

As others have said, you need も in there, as well as possibly addressing her honorifically (さん)

人 (じん) means "person", so you only use it when you need to specify a person. So when you talk about a place, you put "person" there to mean "a person of that place". Here, you don't need it.

You don't use it everytime.

いいぇ、think of the addition of "mo" as "also", as i believe you can have "watashi wa mo-" in a sentence if i understand it correctly.

Yes, it's a particle used to emphasize inclusion of an object in a topic/list.

In these exercises, those times where 学生 is at the start, it's actually also after the subject. In Japanese, the subject is often omitted if it's obvious from the context.

学生ですか？ is actually (あなたは)学生ですか？

You should be able to leave it off. If you said マリアも学生です (Maria mo gakusei desu) and it wasn't accepted, it's worth an error report.

There are very few cases you will be able to get away with not using an honorific. Though it should be noted that you could get away with using ちゃん if say Maria were you're daughter.

Because さん does NOT mean "Ms." It's an honorific suffix used to show respectful deference to someone of similar social stature. "Ms." can sometimes be used for that purpose, but for one thing, it's gendered while さん (typically) isn't, and another, the use of "Ms." varies a lot by country/region and culture so it doesn't always line up with the usage of さん.

Becuase Japan almost always uses some honorific, and for adults that honorific is almost always 「さん」. The only time you wouldn't use an honorific would be if you are VERY close friends with that person.

か is used to indicate a question and can be used with any subject pronoun, though a question with no stated subject pronoun is usually being asked directly to the person you're speaking to (implying "you").

がくせいですか？ (gakusei desu ka?)

Are you a student?

But it could also be "is she a student?", "are they students?", etc. in the context of a conversation.

What is kanji signs

Please try to read the other comments before posting. As many others have already mentioned, さん is an honorific suffix which is used to show respect to the person you are talking to/about. It is optional, but unless you are very confident in navigating Japanese conversation, it is highly recommended that you use さん for everyone except yourself.

Just noticed Arctic_Line's post above in reply to Tara302739 in that the "san" honorific would almost always be used unless you were very very close with the person you were speaking with. That said, when learning to translate it should likely be more specific and not expect the reader to have context. Who's to say I don't know Maria well enough to drop the "san" :)

It should be accepted.

も replaces は, so you can't use them together.

From Kawa Kawa Learning Studio:

You cannot combine は wa, が ga, and も mo with one another.
