CBSE Grade 12 — Chemistry, in English
CBSE Grade 12 Chemistry: 90 of 90 topics written, 3 of the 7 in the open sample readable in English. Counted from the register, not claimed.
In the register this course is cbse-grade-12-chemistry. Cite that, never
the board and grade alone: two registries share every grade id and
number their lessons differently.
| What | How many | What that means |
|---|---|---|
| Topic slots registered | 90 | The season's shape, decided. A numbered slot is a container, not a lesson. |
| Topics written | 90 | Every slot has a heading. |
| Open to read without an account | 7 | Written, and readable by anyone. The rest of the season is written and withheld. |
| Written and withheld | 83 | Written, and not in the open chapter. This is not the same number as the slots that have never been written, which is why both are here. |
| Summaries in English | 11 | 3 of them on a topic anyone may read. |
| Short films | 13 | 0 on a topic anyone may read. Films are counted once for the course, not once per language, so this page cannot tell you which language a film speaks. |
| Slide pictures in English | 0 | No deck has been rendered in this language. |
| Source documents filed | 90 | What a topic's words are generated from. One per topic, where it exists. |
