Here's what typically hurts IGNOU Solved Assignment quality — and what to avoid:
Content issues
Copy-pasting straight from books/study material — IGNOU evaluators specifically check for this. Answers should be written in your own words, even when the concept comes from the block/unit.
Downloading "solved" PDFs from websites and submitting as-is — many students submit identical copies from the same source, and evaluators notice repeated answers across submissions. This can lead to rejection or a very low mark.
Ignoring the actual question asked — IGNOU questions are often specific (e.g., "critically analyze," "discuss with examples," "compare and contrast"). Writing a generic answer on the topic without addressing the specific angle loses marks.
Missing word limits — going far under or over the prescribed word count (or page limit) is penalized.

Structural issues
No introduction/conclusion — answers that just dive into content without framing or summarizing look incomplete.
Not using headings, sub-points, or diagrams where relevant — IGNOU evaluators reward organized, readable answers, especially for long-answer questions.
Skipping examples or case studies — especially in management, social science, and education courses, IGNOU expects applied/contextual examples, not just theory.
Formatting/submission issues
Wrong front page format — missing your enrollment number, program code, course code, session, study center, or assignment code.
Not following the assignment's specific instructions (e.g., "answer in about 500 words each," "attempt any 5 out of 8")
Submitting past the deadline — IGNOU assignments have strict cutoff dates before you're allowed to sit for term-end exams.
No page numbering or question numbers not matching the assignment question paper
Referencing
No references/bibliography — even at UG/PG level, citing your source material (block name, unit, page) or additional readings adds credibility.
If you follow these steps before writing IGNOU Handwritten Assignment then you will definitely score better in your all subjects.
