You can change the grading scale by adjusting the percentage ranges for each letter grade. For example, you can increase the percentage range for an A grade from 90-100% to 93-100% to make it more challenging to achieve an A. Similarly, you can decrease the percentage range for a D grade from 60-69% to 60-64% to make it easier to fail. It's important to communicate any changes to the grading scale clearly to students and ensure that it aligns with the learning objectives and expectations for the course. **

Unfair grading can be frustrating and demotivating, especially when you feel that your efforts and abilities are not being accurately reflected. It's important to address any concerns with the teacher or professor to understand their grading criteria and seek clarification on any discrepancies. Additionally, seeking support from classmates, tutors, or academic advisors can provide additional perspective and guidance on how to improve your performance. Remember to focus on your own growth and learning, rather than solely on the grade itself. **

Yes, a teacher can change the standard grading scale within their own classroom, as long as it is in line with the school or district's policies. However, any changes to the grading scale should be communicated clearly to students and parents to ensure transparency and understanding. It's important for teachers to consider the potential impact of changing the grading scale on students' overall performance and to make adjustments accordingly. **

Issues with lecturers can have a significant impact on exam grading. If lecturers are not properly trained or experienced, they may not accurately assess students' understanding of the material, leading to unfair grading. Inconsistent grading standards among different lecturers can also result in disparities in students' grades. Additionally, if lecturers are not timely in providing feedback or clarifications on exam questions, students may not have a clear understanding of their mistakes, hindering their ability to improve in future assessments. **

It is unethical and against academic policies to change grades after the grading deadline. Grades are typically final once they have been submitted by the instructor and approved by the relevant academic authorities. Attempting to change grades after the deadline could result in serious consequences, including academic penalties and disciplinary actions. It is important to address any concerns about grades before the deadline and to follow the appropriate procedures for grade appeals if necessary. **

Without more specific information about the grading criteria and the context of the situation, it is difficult to determine if the grading is fair. Fairness in grading depends on a variety of factors, including the clarity of the grading criteria, consistency in applying those criteria, and consideration of individual student circumstances. It would be important to review the specific grading criteria and the work that was graded in order to make an informed judgment about the fairness of the grading. **

Oral grading can be justified in certain situations, such as language learning or public speaking assessments, where verbal communication skills are being evaluated. It allows for a more comprehensive assessment of a student's ability to articulate their thoughts and ideas. However, oral grading may not be suitable for all subjects or types of assessments, as it can be subjective and may not provide a fair and consistent evaluation. It is important to consider the specific learning objectives and assessment criteria when determining whether oral grading is justified. **

It is generally not recommended for a teacher to change the grading scale after the exam has been completed. Changing the grading scale after the fact can be seen as unfair to students who have already taken the exam and may have studied or prepared based on the original grading scale. It is important for teachers to establish clear expectations and grading criteria before the exam to ensure transparency and fairness in the evaluation process. **
