Hello aspirant,
It depends on the specific university or institution you're applying to and the stage of the admission process you're currently in.

Generally, there are two main possibilities:
1. Before Submission:

Most universities allow edits before submitting the application form. This is usually done through an online portal. You can typically correct errors in personal details, academic qualifications, and other relevant information.

2. After Submission:

The ability to edit the form after submission is less common. Some universities might offer a limited correction window for specific fields.

In most cases, once the form is submitted, making changes can be difficult or impossible.

To get a more accurate answer, you can check the admission portal of the university you have applied to or you can contact the admission office directly.
