-
Use several apps simultaneously

Solve problems related to low internet connectivity
That is when document management is performed hastily, leading to mistakes.

-
Scanning software
But they neglect the following aspects:
- Lighting conditions

Clarity
-
Blur
Consequence:
The document looks fine on students' phones, but not when assessed.
Importance:

Evaluators might have trouble reading the responses
-
Key information may be overlooked

The mark could be influenced negatively
Alternative Strategy:
Use online resources such as oncepdf.com to improve the quality of scanned files.
Error 2: Incorrect Page Sequence
When writing an exam, students normally:

Combine them swiftly
However, they miss out on:

Checking order
Consequence:
Responses will be in an incorrect sequence, misleading the examiner.
Actual Effect:

Marks deduction for misinterpretation

Unfinished evaluation
Solution:

Incompatibility
This segmented workflow is one of the biggest silent threats.
