Hi,

I was working as a business analyst in a IT firm. I left my job in 2013 as a business analyst. Have around 7yrs of experience as a BA. 

I want help to update myself before I plunge in. Since its been 8yrs gap, please guide me how I should start preparing, what are the latest tools and technologies that I need to know and if any courses you suggest. 

looking forward for help.

Thanks in advance.
