Engineering entry rules

Enter answers using an engineering prefix when appropriate. Type 10 k or 10k, not 10000; type 100 m or 100m, not 0.1.

Units ModeRequire correct units in numerical answers

Units optional.

When Units Mode is enabled, include the correct unit, e.g.: 12mA, 12 mA, 12 mV, 12 kΩ, 12kΩ, or 12mW. For resistance, O, Ohm, Ohms, and Ω are accepted. Spaces are ignored.

u and µ both mean micro. Capitalization matters for both prefixes and units: M = mega, m = milli; mA is valid but ma is not when in Units Mode.

Calculated numerical results allow ±0.5% rounding error. Prefix and answer-format rules still apply.

Practice controls

Use the topic menu to focus on one subject. The score stays cumulative when you change topics or reload the page.

For multiple-choice questions, press A–D to select one answer. Press Enter to check it, then press Enter again for the next question. A skipped question counts as incorrect.
