Planning to learn New Courses like Salesforce Certification.

Hello Everyone,

I am planning to learn Salesforce Certification Training, but I can't find the best modules for great learning.

I just know that  Salesforce Certification will start by learning how to create activities, manage leads, and develop your prospects and sales pipeline using opportunities and accounts, and then understand how you can enhance marketing activities using campaigns. 

Is there anyone help me to solve this problem?
