Student/college help

Hello, I am a college student in a web design class. I already know a little about HTML5 but not a lot. In the class we are going to be using HTML and css coding and have to mainly manually type it up. I was wondering, do you have an tips for a beginner like me? And how long did it take for you to become well/efficient at coding. Thanks a bunch for reading and I hope to get a few responses. - Bethany
