Thank you for the quick delivery! I am already reading through, so I will let you know if any correction is needed. I will review it to let you know if it's okay or not. I hope my teacher will be satisfied with the assignment this time prepared by your team as it seems very good and I'm personally getting fed up of requesting for the modification every time with other sites. GREAT JOB.
