This page is home to every tool we build at PastPapersInside. The goal is simple: help you get reliable answers faster, with less guessing and less spreadsheet work. Whether you are converting grades, estimating an admissions GPA, or planning your revision, the tools here are designed to be quick, accurate, and easy to use.
If you have never used a study tool on our site before, start with the short guide below. It explains what the tools do, how we build them, and how to get the most out of them. You will also find a roadmap that shows what is coming next and how to request a tool we do not have yet.
What you will find on this page
Right now, this page lists two tools that are live and ready to use. We are actively building more. The line-up will grow over time, but the core idea will not change: each tool focuses on one task, gives you a clear result, and explains what is included and what is not.
Expect the following from every tool:
-
A simple input form that matches how you already track your work
-
A result that is easy to read and easy to share
-
Short notes that explain rules, edge cases, and rounding
-
An export or copy option when it makes sense
If a policy changes or a grading rule is updated, we update the tool. You should not have to worry about whether the math still holds.
Why a dedicated tools hub helps
Students use a mix of boards, scales, and policies. A small change in a conversion factor or a rounding rule can shift your results. A central hub solves three problems at once:
-
You know where to find the latest version. Instead of bookmarking separate pages and guessing which one is current, you can return to the hub and follow the link to the specific tool you need.
-
You can compare methods. Many calculators look similar but apply different rules. We document what each tool does so you can decide whether the method matches your situation. If your school or board has a different rule, you will see that in the notes.
-
You can request what you need. The hub is the right place to ask for a feature or a new calculator. We add tools based on student requests and common pain points we see during exam seasons.
Our approach to accuracy
Accuracy is not only about arithmetic. It is also about using the right inputs and the right rules. Here is how we try to keep your results trustworthy:
-
We mirror official policies where they exist. If an organization publishes a conversion table, weighting scheme, or credit definition, we use it and cite it in the tool notes.
-
We handle common edge cases. Examples include pass or satisfactory grades that should be excluded, withdrawals that only count if punitive, and quarter credits that must be converted to semester hours before you calculate quality points.
-
We test the math. Where possible we include simple self-checks or examples. If you type in the example data, your result should match the expected answer.
-
We minimize hidden assumptions. If a choice has to be made because rules vary by school or region, we say so in plain language.
If you think a rule is different in your case, use the request form at the end of this page. Tell us the rule your school or board follows and we will look at it.
Current tools
Below is a quick overview of the two tools that are available today. Open each one for full instructions, notes, and examples.
LSAC CAS GPA Calculator
Quarter × 0.67
CSV export
This calculator estimates your LSAC CAS GPA on the standard 4.0 scale used by the Law School Admission Council. It is designed for applicants who want to see a realistic GPA estimate before they submit transcripts. The calculator accepts course-by-course input and explains how each grade is treated.
What it covers
-
A+ counts as 4.33 on the LSAC scale
-
A, A-, B+, and the full range of grades down to F are handled using LSAC’s conversion table
-
Quarter credits are converted to semester hours at 0.67 before calculating quality points
-
Pass, satisfactory, and credit grades are excluded from hours and from the GPA
-
Failing marks in pass or credit systems count at 0.00 if credit was attempted
-
WF appears only if your school treats it as punitive; otherwise it is excluded
-
Repeated courses are included when both attempts appear on your transcript
What you get
-
An estimated LSAC GPA rounded to three decimals
-
Total included hours, excluded hours, and quality points
-
Worked examples you can copy into the calculator to verify the math
-
A short summary you can copy or export
When to use it
-
You want to know where your GPA stands before you choose where to apply
-
You have credits from multiple institutions and you want a consistent method
-
You learned on quarter credits and need to compare with semester systems
What to keep in mind
This tool gives you an estimate. LSAC calculates your official GPA when they process your transcript. If your school has unusual notations or local policies, read the notes in the calculator so you know how those marks are treated.

We also host a second tool that focuses on a common study task. It follows the same approach as the calculator above: clear inputs, clear outputs, and a short note on rules or assumptions. The second tool helps with an everyday problem students face during the term. Depending on your needs, that might be planning, converting, comparing, or estimating. Open the tool from the list on this page to see the details and try a quick example.
If you want this section to reference a specific tool by name, tell us what it is and we will tailor this page so the description matches what you see on screen.
Strategies
Practice Tips
How to choose the right tool
Picking the right tool is the fastest way to get a useful answer. Use these tips to avoid confusion and rework:
-
Match the method to the decision. If you are preparing admissions documents, use a tool that mirrors the organization’s rules. If you are planning coursework, use a tool that mirrors your school’s grade weights and rounding.
-
Check units and scales. Many results depend on whether your credit is semester, quarter, or another system. If you are not sure, look at how your transcript labels credit hours and choose the matching unit in the tool.
-
Read the notes. The short notes under each tool are there to prevent mistakes. They spell out what is included, what is excluded, and which edge cases are special.
-
Use examples to verify. If a tool offers a worked example, type it in and confirm that your result matches. This takes a minute and gives you confidence in the calculation.
-
Export for later. If the tool can export a summary, use it. This helps when you want to compare outcomes across different scenarios or share your numbers with a counselor.
Common mistakes and how to avoid them
Even a good calculator will produce the wrong number if you give it the wrong inputs. Here are mistakes we see and how to avoid them:
-
Mixing units. Enter quarter credits as quarter credits. The calculator will convert them. Do not convert by hand and then select quarter again.
-
Including grades that should be excluded. Pass or satisfactory grades are often excluded from hours and GPA. Read the note that explains which non-letter marks count.
-
Dropping repeated attempts. Many organizations include all attempts that appear on a transcript. If the rule says to include both, include both.
-
Using the wrong rounding. Some tools report a result to two decimals, others to three. Use the precision shown in the tool when you compare your number to examples.
-
Skipping policy notes. If a withdrawal only counts when it is punitive, you need to know whether your school treats it that way. The notes will tell you how to think about it.
If you follow these tips, your results will match what the tool is designed to produce.
How we build tools
We keep the build process straightforward so the tools are stable and easy to maintain.
Research
We begin with policy research and source documents. If a board, council, or university publishes a rule, we use it. If rules vary, we explain the most common approach and call out exceptions.
Design
We design the input form to match the way students already track results in spreadsheets or notebooks. That reduces friction and lowers the chance of input errors.
Implementation
We write the calculation logic and test it with example data, including edge cases. Where helpful, we add a self-test or a built-in example so you can confirm the numbers on your side.
Documentation
We add short notes to each tool that explain how the math works and which inputs are included or excluded. If we use a conversion factor, we say what it is. If a rule depends on your school, we say that too.
Updates
If a policy changes, we update the tool. If users report a mismatch, we verify the steps and publish a fix.
What is coming next
Two tools are live now, and we are building more. The shortlist includes:
-
More GPA and grade converters. Converters for common scales, including percentage to GPA, GPA to percentage, and CGPA to GPA for international applications.
-
Planning helpers. Simple, no-friction planners that help you map revision across a week or a term, with light export options when you need them.
-
Past paper helpers. Search and filtering that makes it easier to find the right paper and match it to a mark scheme without digging through folders.
-
Aggregate and eligibility checks. Calculators that combine components using weights that match an institution’s published formula.
If you want something specific, ask for it. A single paragraph that explains your case is enough for us to decide how to approach it.
How to request a tool
We add tools based on the problems students tell us about. If you need something you cannot find, send a short message with:
-
The decision you are trying to make or the result you want
-
The inputs you have available
-
Any rules or policies we should follow
-
A quick example with numbers, if you have one
If it is useful to many students and we can verify the rules, we will try to build it.
FAQs
Are these tools free to use?
Yes. Everything on this page is free and runs in your browser. There is no sign-in.
Are the results official?
No. They are estimates meant to help you plan and study. For official results, follow your exam board, your university, or the organization you are applying to.
Why might my result look different from a number my school gave me?
Schools sometimes use local rounding rules or weights. Our tools follow published rules where available and explain assumptions in the notes. If your school uses a different method, adjust your inputs accordingly or tell us what rule you need.
Can I save my work?
Many tools let you copy a summary or export a file. If a tool stores data in your browser, it will say so. You can clear that data at any time.
Will you add more tools?
Yes. We plan to add more calculators and planners based on student requests and policy updates. Check this page for new entries.
