From a Chinese-Curriculum Background to USNCO Chemistry: What Transfers and What Does Not (2026)
Students from a Chinese-curriculum chemistry background arrive with real strengths and three specific gaps. What transfers, what half transfers, and an eight-week bridge.

When to Start USNCO Preparation: A Grade 9-12 Plan for China-Based Students (2026)
Is Grade 11 too late for chemistry olympiad preparation? What each year from Grade 9 to Grade 12 is actually for, plus the enrolment rule that quietly decides your route.

Why You Keep Losing the Same Marks: A Chemistry Error Log That Actually Works (2026)
Most chemistry olympiad practice is exposure, not diagnosis. A five-way mistake taxonomy, a ninety-second log entry and a re-test ladder that stops the same marks going twice.
-
The USNCO Bookshelf: Which Chemistry Books Actually Match the Syllabus (2026)
No single textbook covers the chemistry olympiad syllabus. A three-layer shelf: one general spine, four topic specialists, and the problem sets where the real gains are.

Structure, Bonding and Periodic Trends: The USNCO Marks You Should Never Lose (2026)
Structure and bonding questions are the fastest marks on a chemistry olympiad paper, and the ones students quietly lose. The trends, the VSEPR routine and the drills that fix it.
-
The Maths Behind Chemistry Olympiad Problems: Logs, Approximations and Sig Figs (2026)
Most lost time on chemistry olympiad problems is arithmetic, not chemistry. The log values worth memorising, when the x-is-small shortcut is legal, and the sig-fig rules that decide marks.

USNCO Electrochemistry and Kinetics: The Under-Trained Pair (2026)
Electrochemistry and kinetics are the two physical-chemistry blocks school courses under-train. One triangle and one selector chart cover most of what questions ask – plus the eight traps.
-
The USNCO Blind Spot: Inorganic and Descriptive Chemistry (2026)
Thermodynamics and organic get all the attention, but inorganic and descriptive chemistry is where AP and IB students lose marks fastest. Five blocks, decoded with worked reasoning.

IChO 2026 in Tashkent: What This Year’s Chemistry Olympiad Means for China-Based Students
IChO 2026 in Tashkent gathered national teams from 80+ countries. How the world chemistry championship works, how its medals are banded, and the honest lesson for students in China.

How Team USA Is Chosen: Inside the USNCO National Exam and Study Camp Funnel
How the USNCO narrows thousands of US students to a four-person Team USA: the National Exam, the study camp, and the citizenship gate China-based students should understand.
