In the 2026 IOLC Newcomer/Junior Division Rongga problem note, bh, mb and ng are recorded as consonants. Learn a data-first method for segmenting unfamiliar multi-letter consonants without over-splitting or over-combining.
Understand how the IOLC team average is calculated from the individual scores of actual participating members, how adding or removing a member changes the mean, and how regional individual evaluation differs from national team evaluation.
Prepare for the IOLC 2027 Level Test (March 7) by simulating the latest source-backed 2026 regional format: three hours, four independent puzzles. Learn how to select a balanced problem set, hold to a strict timing protocol, and diagnose errors with a three-step post-mock review.
Learn how to rigorously test phonological rules in Linguistics Olympiad problems. Discover how to identify conditioning environments, avoid over-generalization, and verify sound changes across all matching contexts—while recognizing that not all changes are conditioned and data alone may underdetermine the answer.
In Linguistics Olympiad number system problems, the base is rarely given. Learn how to infer it from small-number correspondences first, then translate large numbers safely—with checked worked cases and a contrasting failure mode.
Learn how to distinguish grammatical roles from surface word order in IOLC and NACLO problems. Includes a checked worked teaching illustration, contrasting failure case, and preparation strategies for the 2027 season.
