yup, correct. google cannot replace another human being, especially as a sensei.

as a perfect resource location, yes. google can act as a compliment to your studies.

i would actually ask the lecturer himself on what specifically will he be teaching about. and what are his objectives for the course, like for him to teach you the basics ke, or sports photography ke, using photoshop to enhance ke, etc. i'd actually stay away from those general learn all in one minute course, as google is good for that. learn something specific!
