Points needed for letter grade

Many secondary and college courses still grade on a pure total-points system: every quiz, lab, project, and exam adds to one running sum, and the final letter is a percentage of the course total rather than a weighted category average.

Students who know their current points and the course maximum often ask a single practical question before the term ends: how many more points do I need for a B or an A? This calculator answers that with a deterministic total-points model. You enter points already earned, total points possible in the course, and a target letter (A, B, C, or D). The tool multiplies the standard cutoff percentage by the course total, subtracts what you already have, and returns points_needed plus your current percent and letter. Optionally add remaining points still available so you can see whether the target is still reachable if you earn everything left. The same pure arithmetic powers the free browser widget and the API path, so study planners, LMS plugins, and homework demos never disagree on the gap to a letter band.

How to use it

Enter your values in the form above. The tool checks them before calculating and shows the result on the same page.

Check your inputs

Use the labels and units shown next to each field. If something is missing or outside the allowed range, the page points to the field to fix.

Use it again or automate it

Use the browser tool for individual checks and the API when you need the same capability in an automated workflow.

What you can do with it

Enter one set of values and see the result without building a spreadsheet or script.

Compare scenarios

Change one value at a time and rerun the calculation to understand what affects the result.

Automate repeated work

Use the API when the same calculation needs to run inside your product or workflow.

For developers — API access

Everything on this page is available programmatically. This section is for teams who want to wire it into their own systems; everyone else can just use the tool above.

API endpoint

POSThttps://api.kit.forhosting.com/edu/points-needed-for-letter

Prefer to automate it? One authenticated POST creates the task; the result comes back by webhook or a signed link. The same capability also runs here on the web, by email and from Telegram — and soon from our app too.

Call it from your stack

curl -X POST https://api.kit.forhosting.com/edu/points-needed-for-letter \

Example request

{
  "current_points": 650,
  "total_points": 1000,
  "target_letter": "A"
}

Example response

{
  "task_id": "tsk_a1b2c3d4e5f6a1b2c3d4e5f6",
  "type": "edu.points_needed_for_letter",
  "status": "queued",
  "_links": {
    "result": "/tasks/tsk_…/result"
  }
}

The API is asynchronous: the call returns a task_id immediately and the result arrives by webhook. Polling is capped at 1 req/s per task.

Errors

HTTP	Code	Meaning
`401`	`unauthorized`	Missing or invalid API key.
`402`	`insufficient_balance`	Your balance doesn't cover the task price.
`404`	`unknown_type`	That task type doesn't exist.
`429`	`rate_limited`	Too many requests. Use the webhook instead of polling.
