Strokes p/length - do I stink?

I’ve tried searching for the answer to my question but I've been unsuccessful, so here goes – another newbie query: If I’m swimming 24 strokes* per length (75 feet) am I really a terrible swimmer? I’m 5’7” w/what I suppose is an average build… :confused: Any suggestions for improvement? Thanks! Steph *And just to clarify, by strokes I’m referring to swimming freestyle - right hand in equals one stroke and then left hand in equals two strokes, etc., until I reach the end of the lane.
