From any home screen (the screen your presented with when you unlock your phone) the "apps drawer" is accessible from the bottom right icon, that on an unmodified Note 3 looks like a 4x4 grid of tiny squares. Once tapped you'll be presented with your installed and apps or widgets. To change between the two there is a choice at the top of the screen. In an unmodified Note 3 there are two folders amongst the screens of separate apps (swipe between the screens in the app drawer like you can with home screens) one is "Google", where Chrome should be; the other is "Samsung" where Samsung apps are.
