CAS Manager vs a spreadsheet: managing your API score the easy way

Many teachers keep their CAS record in a spreadsheet plus a folder of scans. It works, until the formulas break or a proof goes missing. Here is an honest comparison.

When a spreadsheet is still fine

If you have a handful of entries and a notification that matches a template you already trust, a spreadsheet can be enough. The problems start with many years of data, several categories with caps and a pile of proofs.

When to switch

  • You are unsure whether a cap has been applied correctly.
  • You spend more time assembling the file than doing the work in it.
  • You cannot quickly say which entries are missing proof.

Trying it

New accounts start with a free trial and need no payment details. You can enter a few activities and see the scores, totals and eligibility checks before deciding.
