Higher Certificate in Statistics RSS


I am working in the banking industry doing data analysis to generate insights on various products. I have close to 5 years of experience now and feel I could work towards solidifying the knowledge I have and increase my expertise in solving practical problems in my area of work.

Since I intend to continue working, I came to the conclusion that attempting and hopefully completing the Higher Certificate in Statistics from RSS will help me to learn in a structured way.

I am interested in the experience of someone who's appeared for it/passed it and also good resources/books to use as the reading list for each paper has a bunch of books. Can one or two books do the job of covering most of the things? and are they available online?
