Know the boundary before you study past it.
NEB board practicals. The only free Nepali lab resource found.
NEB-format papers; useful timing drill
Fast cross-referencing
Recommended by Dr. Chen's Academy as the Level-1 companion
Modular; excellent for filling single-topic holes fast
Full general chemistry, calculus-free, IChO-adjacent rigour. The free equivalent of Zumdahl.
Pre-general-chemistry bridge
34 topics: Physical (11) · Inorganic (6) · Organic (10) · Organic Conversion Reactions (3) · Applied (4). The Organic Conversion Reactions section (aliphatic conversions, aromatic conversions, conversion practice questions with solutions) is directly the format of olympiad synthesis problems.

NEB grades 11–12 syllabus bundle
Includes volumetric analysis, titration, gravimetric analysis — which are also named NEB Grade 12 physical-chemistry topics.

Government server, very slow / times out from outside Nepal
Best-in-class for building mechanistic thinking — the skill olympiad organic questions actually test. SkillBuilder exercises.
The famous thin companion. Vol. 2 covers aromatics + IR and NMR spectroscopy — both IChO Level 3 and absent from NEB. Highest value-per-rupee book on this list.
The classic general-chemistry text used for AP and college. Strong thermodynamics and equilibrium — the two heaviest olympiad-physical-chemistry blocks.
"A rigorous treatment of chemistry from a physical chemistry perspective. Essential for students aiming for Study Camp and beyond." Deeper thermodynamics + quantum than any general text.
The gold standard. "Exceptional mechanism explanations with curved arrows… advanced synthesis planning and retrosynthetic analysis." Required for IChO organic, which NEB does not reach.
Covers modern instrumental analysis — IChO §12 Analytical chemistry and §8 Spectroscopy, both entirely outside NEB. The best free route into the largest Nepali syllabus gap.
Integrated organic + inorganic + physical, with strong molecular orbital theory. "Ideal for advanced IChO-level preparation." MO theory is IChO Level 3 and completely absent from NEB.

Full general chemistry, calculus-free, IChO-adjacent rigour. The free equivalent of Zumdahl.
Covers modern instrumental analysis — IChO §12 Analytical chemistry and §8 Spectroscopy, both entirely outside NEB. The best free route into the largest Nepali syllabus gap.
5 sections: ① Synthesis of inorganic & organic compounds (33+ tagged techniques) ② Identification of inorganic & organic compounds ③ Determination of some inorganic & organic compounds ④ Special measurements and procedures ⑤ Evaluation of results. Level tags work the same way — and the rule is explicit: "If the organizer wants to apply a technique which is not mentioned in the above syllabus, this technique is set to level 3 automatically."
12 sections, 326 entries, each tagged Level 1/2/3. §1 The atom · §2 Chemical bonding · §3 Chemical calculations · §4 Periodic trends · §5 Inorganic Chemistry · §6 Physical chemistry · §7 Chemical kinetics (homogeneous) · §8 Spectroscopy · §9 Organic Chemistry · §10 Polymers · §11 Biochemistry · §12 Analytical chemistry. This is the contract you train against.

Draft taxonomy — official transcription in progress
Atomic structure is in NEB Gr.11; Schrödinger equation & quantum numbers are Level 3 — beyond NEB (C-4).
Source: Official IChO Syllabus — Theoretical Part (10 pp, 326 entries) ↗
Valency/VSEPR/hybridization in NEB; delocalization & MO theory are Level 3 — beyond NEB (C-4).
NEB Gr.11 inorganic (14 topics) + Gr.12 transition metals cover most; olympiad depth exceeds the curriculum.
NEB Gr.11 physical (15 topics) + Gr.12 physical (11 topics) align with this section; olympiad depth exceeds the curriculum.
Chemical kinetics is an NEB Gr.12 topic; IChO depth exceeds it.
No NEB counterpart — Level 3 (C-4). Highest Level-3 density in the syllabus.
NEB Gr.11 organic (8 topics) + Gr.12 organic (10 topics + 3 conversion sets) cover the skeleton; mechanisms at IChO level go beyond it.
No NEB counterpart — Level 3 (C-4).
No NEB counterpart — Level 3 (C-4).
Instrumental analysis is outside NEB — Level 3 (C-4). Classical titration/gravimetry live in NEB Gr.12 but not the instrumental core of §12.
Level 3; completely absent from NEB (C-4).
Source: NEB → IChO gap analysis (chemistry research file, C-4) ↗
No olympiad-level practical training material exists in Nepal (C-6); NEB labs are board-level titration/gravimetry only.
