Formula used

Score estimate: weighted percentage = multiple-choice percentage × multiple-choice weight + Create percentage × Create weight.

Bit patterns: possible patterns = 2^bits. Minimum bits = ⌈log₂(states)⌉.

Image storage: width × height × color depth. Audio storage: sample rate × bit depth × channels × duration.

Transfer time: file bits ÷ effective throughput. Packet count uses the ceiling of file bytes divided by payload bytes.

Password combinations: character set size^{password length}. Entropy = log₂(combinations).

Frequently asked questions

Is this an official AP score calculator?

No. It is an unofficial study estimator and cannot predict an official score.

Does the pseudocode tracer run every possible AP CSP program?

It supports a practical educational subset. Complex or ambiguous programs may require manual review.

Why does the list simulator use one-based indexes?

AP-style pseudocode commonly treats the first list element as index one.

Can I use hexadecimal and octal?

Yes. The number-system tool converts binary, octal, decimal, and hexadecimal values.

How is quiz progress stored?

Progress is stored locally in your browser through localStorage.

Does the password tool crack passwords?

No. It only demonstrates combination counts, entropy, and estimated guessing time.

Can the PDF export create a file automatically?

It opens the browser print dialog, where you can choose Save as PDF.

What does throughput efficiency mean?

It estimates the usable portion of advertised bandwidth after protocol and network effects.

Can I save Create task notes?

Yes. Checklist selections and notes are saved locally in the browser.

What is a boundary test?

It checks behavior at a minimum, maximum, empty, or transition value.

Is this tool affiliated with College Board?

No. AP and related terms belong to their respective owners.
