Okay I see you are pretty expert at japanese, thanks for the corrections.
I studied only literature nihongo, I can read Mishima in japanese for example, but there is no way I can talk to japanese, thus I can not improve my oral skills.

>in the second sentence, i cant call into account what you want to say.

i wonder, you want to say, 'Why did they go up such a strange university?' alternatively, 'Why did i go up such a strange university?'
I read somewhere that KAWATTA means strange, no?
for example google this 変わった学生
you will get 変わった質問に困った！茶道で学生が変わった
right? (but yes I fucked okurigana)

’太くなる’means get fat.
I am pretty aware of this, but haven't you studied this grammar:
RU + BAKARI
it means she continues to get fat (even more)
google also pretty aware of this
for example:
細くはならない。太くなるばかりである
おととい引退したばかりですが
but thanks for your correction. I hape one day (probably after living in Japan for some time) I will master my speaking skills.
