| 95% | Logarithm-law simplification / evaluation — Combine with product (+), quotient (−) and power (n·) laws · reduce the argument to a power of the base · evaluate using log_b b = 1. | 3 MARKS |
| 85% | Binary ↔ decimal conversion — Decimal→binary: repeated ÷2, read remainders upward. Binary→decimal: weight each digit by its power of 2 and sum. | 2 MARKS |
| 80% | Modulo / calendar / clock — Translate to N mod 7 (calendar) or N mod 12 (clock) · compute remainder · count forward/backward · name the day/hour. | 2 MARKS |
| 90% | Alligation / mixture — Identify C, D, M · apply (D−M):(M−C) cross-rule · verify by weighted-average · state ratio with units. | 3 MARKS |
| 70% | Boats-streams / pipes-cisterns — Boats: compute down+up speeds, then b=(d+u)/2, s=(d−u)/2. Pipes: convert to rates, sum (leak negative), invert. | 4 MARKS |
