Real standards. Real work. Real results.
The way school should be.
Direct academic study guides in grammar, writing, and literature for grades 9–12. No filler. We do not soften the work.
We do not soften the work.
Built on the standard of Clarence Thornbrough Terry — principal, teacher, Signal Corps — and Mary Lee Thompson, who taught for thirty years and did not accept sloppy work. Neither do we. These guides do not water down the material for the age group. They teach high schoolers to write above grade level and defend an argument with evidence.
Three Guides. Nine-Plus Sections Each.
Every guide: concepts, side-by-side examples, a practice set, and a full answer key.
Writing Essentials
Thesis, essay architecture, the PEAL paragraph method, evidence and MLA, revision. Model paragraphs, 12-question practice, answer key.
Literature Essentials
Summary vs. analysis, close reading, theme, character, devices, symbolism, the analysis essay. Model analysis, 14-question practice, answer key.
How It Works
1
Read the rule.
Concepts in plain, direct language — no filler.
2
Study the contrast.
Every concept shows the wrong version next to the right one. That gap is where the learning lives.
3
Do the practice cold.
Then grade yourself against the key. The mess is part of the data.
