This class was a dead loss!... I almost fell asleep during it;-)
On the other hand..." What an amazing class I was so into it!" I got so much form it
It's good to express how we truly feel and although honesty is the best policy...
it can be a little cruel sometimes;-))
Disappointment has many phrases attached to it!
From the blunt..."That class sucked!"
to the more humorous..."What a snore fest!" or Boredom City!
感じていることを正直に表現することは良いことで、正直であることはやり方としては最良ではあるけれども・・・
ときおり少し残酷になりえますよね。
がっかりしたときのフレーズはたくさんあります！
"That class sucked!"
（あの授業はクソだった！）というぶっきらぼうな言い方から、
"What a snore fest!" or ”Boredom City!”
（「いびき大会だった！」あるいは「退屈な町！）というよりユーモラスな表現まであります。
You can say:
Class was boring today.
This is an informal phrase used to say that the class was not interesting or stimulating.
This form makes it seem slightly more positive and polite:
Class was really easy today.
I wasn't challenged much in class today.
When you are not challenged, it means that you did not find the work difficult to understand. It did not make you think hard.
You can also say:
They spoon fed us in class today.
To spoon feed someone - To make something too simple for people to understand and teaching it to them.
I hope that helps!
こう言うことができます。
Class was boring today.
これは授業が面白くなかった、刺激的でなかったと言うカジュアルなフレーズです。
こちらの言い方は、もう少しポジティブで丁寧な印象です。
Class was really easy today.
（今日の授業はとても簡単だった。）
I wasn't challenged much in class today.
not challenged というのは、そのタスクがあなたにとって理解するのに難しくなかったという意味になります。頭を使うことがなかったということです。
このように言うこともできます。
They spoon fed us in class today.
spoon feed someone - 相手にとってわかりやすく噛み砕きすぎて、それを教えること
