Repeated Course GPA Calculator

About the Repeated Course GPA Calculator

Retaking a course can significantly improve your GPA, but the impact depends on your school's repeat policy. Some schools practice grade replacement (the new grade replaces the old one in GPA calculations), others average the two grades, and some count both attempts. This calculator models all three scenarios.

Enter your current GPA, total credits, the course details (credits and original grade), and the grade you expect on the retake. The tool shows your GPA under each of the three common repeat policies, making it easy to understand the potential benefit.

Retaking a course from D to A can boost your GPA substantially, especially if you're early in your academic career with fewer total credits.

When This Page Helps

Before investing time and tuition to retake a course, you need to know the GPA payoff. This calculator shows exactly how much your GPA will improve under your school's specific repeat policy, helping you decide whether the retake is worthwhile.

How to Use the Inputs

1. Enter your current cumulative GPA (including the original grade).
2. Enter your total earned credits (including the original course).
3. Enter the course credit hours and the original grade.
4. Select the grade you expect to earn on the retake.
5. Compare your GPA under three repeat policies.
6. Check which policy your school uses for the accurate result.

Example Calculation

Tips & Best Practices

• Grade replacement policies are most generous — check if your school offers this.
• Some schools limit grade replacement to the first retake only.
• Check if there's a limit on how many courses you can retake for grade replacement.
• Retaking early (fewer total credits) gives a larger GPA boost.
• Even under "both counted," the new grade still improves your GPA if it's higher.
• Financial aid may be affected — retaking already-passed courses might not count toward aid.

Common Repeat Policies

The three main repeat policies are grade replacement, grade averaging, and both-counted. Grade replacement is the most common at community colleges and state universities. Many schools allow grade replacement only for grades below C. Some elite institutions count both attempts, which provides less GPA benefit.

Strategic Retaking

Retake the courses where you'll see the biggest improvement. A jump from D (1.0) to A (4.0) is worth 3.0 quality points per credit — much more impactful than B− (2.7) to A (4.0), which is only 1.3 quality points per credit. Focus on your lowest grades first.

Transfer Credit Implications

When transferring, the new school recalculates your GPA using their own policy. Some accept the grade-replaced version, while others recalculate with both grades. This is important to consider if you plan to transfer.

Frequently Asked Questions

• What is grade replacement?

  Grade replacement means the old grade is excluded from GPA calculations and replaced by the new grade. You still see both on your transcript, but only the new grade counts toward GPA. This is the most GPA-friendly policy.

• Do all schools offer grade replacement?

  No. Community colleges commonly offer it, many state universities do, but some private universities count both attempts. Always check your school's academic catalog for the specific repeat policy.

• Can I retake a B to get an A?

  Policies vary. Some schools only allow retakes for grades below C. Others allow retaking any grade. Even where allowed, grade replacement may only apply to grades below C, with the new attempt counted as additional credits for B or above.

• How many times can I retake a course?

  Most schools limit retakes to 2–3 attempts total. Grade replacement is often limited to the first retake. Financial aid typically doesn't cover more than two attempts of the same course.

• Does the original grade still appear on my transcript?

  Yes, even with grade replacement, both the original and retake grades appear on your transcript. However, the original is marked as excluded from GPA with a notation like "R" (repeated).

• Is retaking a course worth the cost?

  It depends on the GPA improvement vs. the tuition cost. Retaking a D (1.0) to earn an A (4.0) in a 3-credit course can raise your GPA by 0.15 or more with grade replacement, which could affect scholarship eligibility and honors standing.
