This question is in reference to my question here How to know which journal is open access?
I came to know from my previous question that there are journals which are hybrid journals i.e. they support open access and at the same time they have issues which dont charge fees from the author.
Now the question is what is the difference in publication process of the two ways in the same journal?
Suppose that I submit a paper in the journal "Discrete Maths" which supports both ways. So what will be the process of my paper getting accepted/rejected go through when I submit through open access and when I dont submit through open access?
Does the paper go through the same process if I pay the fee or it goes through a different process?
And if it goes through the same tedious process why should the authors pay a large sum of money for it?
I am completely new in this field.So any help will be beneficial.
