Question

how can i say "no design or minimal design with significant errors"

Answer 1

Here are several alternative phrasings you can use, grouped by tone/context:

Concise/rubric-friendly
- "No design or minimal design with major errors"
- "No/Minimal design; significant errors"
- "Design absent or minimally developed; critical errors"

Formal
- "Design is absent or only minimally developed and contains substantive errors"
- "Either no design is provided or the design is minimal and fundamentally flawed"

Plain/informal
- "No design, or just a tiny one that's full of mistakes"
- "Either there’s no design or the little design there is has serious errors"

Neutral/diagnostic
- "Design missing or inadequate; contains significant flaws"
- "Insufficient design development with substantial errors"

Pick the one that best fits your audience: use the concise/rubric options for grading rubrics, formal ones for reports, and plain ones for casual feedback.
