I found the article very informative.
I can always tell when the author is from India because they use the
word "would" a lot. Most Americans would write "Passing the exam would demonstrate" as "Passing the exam demonstrates". "The exam would be within the scope" would be written as "the exam is within the scope". I understood what she meant, though.
I would change "Drag and Drop(D & D)" to "Drag and Drop (D & D)" (add a space before the left paren. Also, I would change "if you need to make any modification" to "if you need to make any modifications" (but either is correct).
Thanks for the article!
