How well does R.I.A. cover the topics and issues at hand?

R.I.A. goes in-depth with all the material it provides and I am never left with a question unanswered.

R.I.A. moderately lists what is necessary and is sufficient in its information.

R.I.A. needs some work on getting some small matters clarified.

R.I.A. has tremendous problems with extent of coverage, and I am often left stumped on what to do.
