Remote Chess Academy?

For a beginner, is RCA (Igor Smirnov) a reasonable tool for a beginner who would like to pass 1000 OTB?  Specifically, has anyone personally used the "Level Up Your Chess" course and been satisfied with it?

Give Danya Naroditsky's speed run series or John Bartholomew's climbing the rating ladder series a watch.
I went from 600 to 2100 before I ever bought a single course. Although I did pick up two books (100 endgames you must know and How to Reassess Your Chess).
A few coaching sessions to give you direction, a study plan and some game analysis would also go a LONG way.
For someone below 1000, really, the main focus should be tactics and basic endgames IMO.
