Hi,
I am writing this to draw you attention and implore all senior members of this page that I am about to complete my Masters shortly. I had ambition to attempt CSS in future and the time has come.
I reviewed whole syllabus. I am mingled with various assumptions like I do not possess sufficient ability to deal mathematical subjects. Other than compulsory subjects, can I choose subjects of my interests and ignore those I do not find competent in?
How many subjects I will have to attempt in the exam?
How much time is required for the preparation?
And what other aspects are essential for me to understand while preparing?

Thank you in advance for all the support.
