I don't think it's an issue of the focus on grading/getting the right answers, more a lack of focus, when teaching units, on getting coherent results, in regard

  >in regards of the units: for example not multiplying a distance and a time to get a speed and so on. From my own personal experience it was exactly units like velocity d/t and pressure m/a or things like volume d^3 that I made the most mistakes on while I learned. Especially when it came to having to convert between different units within an equation. The only thing that really helped was practical experience working with real world units and geometries. I think one of my bigger problems was being unable to clearly visualize what it was the units actually represented. It wasn't until I started having to calculate distances, speeds and areas on maps, culvert diameters and volumes, water pressure through tunnels and actual 'real things' that I really started to understand and stopped making errors with units. But it took quite a while and it was only after 5 years or so at my last job of working with units and measurements every single day that I really became very comfortable with working with them.
