Hello
Do you want me to help you on this?
I need to ASK because i had spent quite a time of mine, assisting you with your questions issue before (when your questions were getting closed due to subscription issue), where you actually requested me the same question. And that actually helped you.

But when you opened this question, you didn't write "For Dr. Amit" before your question, as i clearly informed you to.

So let me know what exactly you want. If you don't want me to help, let me know clearly as i don't want issues later on when you need to Click"Rate the answer" so that i get paid for my time spent answering you.

Yes I would like your help. I thought there was a specific area to request someone and did not know how to deny another expert's help when automatically assigned.

Alright.. But that's why i asked you to write "For Dr. Amit" before your question (in the heading)
That way you are directly requesting me and only one expert gets assigned.

I had started working on this already. Just a couple of minutes to go.

This was a practice exam and that was not worth points thankfully; however, was automatically graded and resulted in a 75%. So some of the answers were wrong. It does not show which ones were incorrect so I have no idea what the correct answers to these could have been. I will still pay for this but just note that they were not 100% correct.
