I have been working as an academic author for the past couple of years. My major contribution was creating quality questions (mainly MCQs), which were mostly error-free. Most of the subjects that i worked on involved maths and engineering titles. Developing problems and their solutions were an important part of my work.
I can assure you that you won't have any issues with the quality of questions. Also, i can deliver work as per the requirement within the specified time, all in the most systematic manner possible.
Looking forward to working with you!
