All fields of life have been affected in COVID-19 spread, but the education sector has been the most affected one. And there are no signs of schools opening far away. Millions of people involved in education have lost their jobs. It is said that necessity is the mother of invention.
Coronavirus has proved it right! Teachers are delivering lectures online, students are acquiring assignments experts, and experts are getting paid for the tasks.

I think it is the best substitution for teachers who were laid off by their administration to compensate for the loss. What do you think about this?

Students have lots of issues in academics because they have many burdens of academics and it is very important for them. They never skip any work because If they skip any work so teachers give them bad remarks in the work so therefore every student do the hard work to getting good remarks. Well, nowadays many medical students are very troubled about the subject of Physics. The subject is very hectic, boring, and time-consuming. Mostly students face issues in numerical because it is very technical and it need the best skills that do not have with every student. Some of the students also take online help with experts where every student hires to write my assignment at cheap price. But, every time they do not afford them and now they want to get perfect solutions. They want that somebody provides the numerical tips that how to solve physics numerical.
