Terms & Conditions

1. About BuyISmart

BuyISmart provides online tools and educational resources designed to help people work through common grading and calculation questions.

The website may include tools such as the Easy Grader , Grade Calculator , Test Grade Calculator , Weighted Grade Calculator , Final Grade Calculator , grade charts, score converters, GPA conversion tools, and other calculators.

The exact tools and features available on the website may change as BuyISmart develops, improves, replaces, or retires individual tools.

2. Acceptance of These Terms

By accessing, browsing, or using BuyISmart, you acknowledge that you have read and understood these Terms & Conditions and agree to follow them.

If you use BuyISmart on behalf of another person, organization, school, business, or other entity, you confirm that you have the authority to accept these Terms on that party’s behalf.

If you do not agree with these Terms, you should stop using the website.

3. Eligibility and Responsible Use

You may use BuyISmart only when you can legally agree to these Terms under the laws that apply to you.

You are responsible for using the website in a lawful, respectful, and reasonable manner.

4. Using BuyISmart Grade Calculators

BuyISmart’s calculators are designed to perform common mathematical calculations. These may include test scores, percentages, letter-grade conversions, weighted course grades, final-grade requirements, grade projections, and related calculations.

The result depends on the information you enter and the calculation method used by the tool.

Before relying on an important result, check that your inputs match your course or assessment rules.

Examples of information that may affect a calculation

• Total questions and correct answers.
• Points earned and points possible.
• Assignment or category weights.
• Current course grade.
• Final exam or remaining-work weight.
• Target percentage or letter grade.
• Custom grading scales.
• Extra credit, dropped scores, curves, or other special rules.

For example, a question-based test with equally valued questions may use correct answers divided by total questions. A weighted course grade requires a different calculation. Using the wrong calculation method can produce a result that does not match the official gradebook.

5. Grading Scales and Grade Interpretations

BuyISmart may provide standard or example grading scales for illustration and calculation purposes. These scales are not intended to represent every school, instructor, university, country, examination board, or educational system.

A percentage and a letter grade are not always interchangeable across institutions. One course may use plus and minus grades, while another may use different percentage boundaries.

When your instructor, institution, or course syllabus provides an official grading scale, that official source should control.

You can review the available grading-scale tools on our Grade Scale Calculator page.

6. Educational and Informational Content

BuyISmart may publish explanations, examples, formulas, guides, and other educational material about grade calculations and related topics.

This content is intended for general informational and educational use. It does not replace instructions or decisions made by your teacher, school, college, university, testing organization, academic advisor, or another authorized institution.

When an official policy or instruction conflicts with information published on BuyISmart, follow the official source that governs your situation.

For additional information about how calculator results should be interpreted, please read our Disclaimer .

7. User Inputs and Responsibility

You are responsible for the information you enter into BuyISmart tools.

A calculator cannot determine whether the information you entered matches your instructor’s grading policy unless the tool explicitly asks you to provide those rules.

Before using a result for an important decision, review your inputs and compare the calculation with the official information provided by your course or institution.

8. Privacy and Personal Information

Your use of BuyISmart is also subject to our Privacy Policy .

Please review that policy to understand how BuyISmart may handle information relating to website visits, cookies, analytics, communications, advertising, and other privacy matters.

Unless a tool specifically requires personal information, avoid entering unnecessary sensitive information into a calculator.

BuyISmart does not ask users to place confidential academic, financial, health, authentication, or other sensitive information into a calculator merely to perform ordinary grade calculations.
