Is there a better way to say "marking randomly"?
If a school teacher did not really read a pupil's exam work but just put down ticks and "x"s randomly. How to say that in English naturally?
The teacher didn't mark my exam work carefully but carelessly?
Is there any other way to make it sound better?

Another question. When I was applying for a job they asked me to write three book reviews each with 600 words.
I didn't write them seriously but just quickly typed enough words to reach the word count knowing the employer wouldn't really read it carefully. How do I describe what I did as briefly as possible?

I didn't write it nicely but just mucked around to reach the word count?

Thanks in advance.

Answer

1.  “Randomly” suggests that the teacher’s eyes were closed or that the teacher otherwise did not pay any attention at all.  If you are trying to say that the teacher did a rushed, careless, or sloppy job, you could say the teacher marked my exam carelessly, hastily, sloppily, or “in a half-assed way.”    2.   “I just dashed off the three essays” is a good way to say you wrote them quickly.

Thanks that helps。

Answer

In conversation with friends, you can also say "the teacher bullshitted his/her grading" and for the second situation, you "bullshitted the essays". It's a really common way students here say they didn't put much effort into essays and just made things up in order to take up space. "Bullshit" IS A CURSE WORD though, so you'd only want to use it with friends.
