Can I link a sentence ending in です with a ます sentence?


I want to translate 'I am a third year junior high school student and I am
studying maths. Is this correct:

私は中学三年生で、すうがくを勉強します。

Please give me a correction if this is incorrect. Thanks in advance!!




Yes, you can join two or more sentences using the te-form regardless of
whether they end with ます or です.

Your attempt is grammatically perfectly correct, but is semantically a little
weird because すうがくを勉強します would sound like "I ( _will_ ) study math". To say "I
_am studying_ math," you have to use the [progressive
form](https://www.wasabi-jpn.com/japanese-grammar/present-progressive-tense-
resultant-states-with-te-form/).

> 私は中学三年生で、数学【すうがく】を勉強しています。
