how long does it take to grade a test i been waiting for the longest
Have you PMed an Administrator or Teacher yet? If you hadn't, then it's no wonder why you've been waiting for so long with no results. If you have, then that's not in my area to answer.
do like sending my exam to the administrator i did
I must've missed it, I'm sorry. It'll be graded very soon and you'll be placed in a dorm within 5 minutes of the test grading.
Again, I am sorry.
