What shoiuld I opt in qlik sense

Hello there,

Please forgive me and provide kind assistance if I have posted to the wrong subsection!

I have a good interest in learning qlik sense certification and right now I am taking help from various platforms like https://www.qlik.com/us/products/qlik-sense

Also I have a doubt that is it a good option to learn from platforms like this or I should go for some qlik sense training . I have searched for the solution of my queries in various above platforms which helped me up to some extent only as it was not directly given by any expert or trainer.

Hoping in getting a quick response

Thankyou in advance.
