New to Scrum

Hi all,

I am new to the concept of Agile/Scrum but would definitely like to pusue some further training

Are there any online courses I could enrol on which would prepare me for a Scrum exam?

I come from a traditional developement background (25 plus years of developing business applications on the AS/400) and this methodology is rather alien to me as my previous roles have involved 'waterfall' development but I have recently undertaken some Agile courses with a previous employer

What would be the best certifcation to undertake when coming into Scrum for the first time?

Regards,

David Bryan
