Are you looking to work on anything specific? Just asking for beginner exercises is a bit broad, but try stuff like chromatics & major scale/minor pentatonic patterns to start as really general 'beginner' stuff.

Just do your scales, and look on Google. They usually have some good stuff. You could find tabs on UG.
