Course synthesis
Synthesize in 15-30 minutes a dense course (handout, textbook, video) into an actionable note for revision and application.
Students must absorb 100 to 300 pages weekly. Reading passively is insufficient: what isn't synthesized is forgotten 80% in a week. AI lets you produce in 15-30 minutes a dense, structured synthesis of a course, vs 2-4h manually. The challenge: synthesis truly captures essentials without losing nuances, and is condensed enough to reread in 5 minutes before exam.
Step-by-step workflow
Choose the right source
Official handout > reference textbook > class notes > recorded video > professor slides. The more official the source, the more reliable the synthesis.
Submit to AI with context
Specify level (BA1, BA3, MA), subject, assessment type (oral, written, MCQ, dissertation). Synthesis format changes by parameters.
Request 3-level synthesis
TL;DR (3 lines), medium summary (1 page for revision), detailed (2-3 pages for understanding). Having all 3 enables deep or skim reading.
Verify critical concepts
On technical subjects, AI may oversimplify or err. Always cross-reference key definitions and formulas with the official handout.
Activate synthesis with questions
Reading passively = forgetting. Have AI ask 5-10 questions after reading, explain concept aloud (Feynman technique), or produce Anki flashcards.

3-level synthesis
You're a tutor. Synthesize this course: **Subject**: [SUBJECT] **Level**: [BA1, BA3, MA2...] **Topic**: [TOPIC] **Raw course**: [PASTE OR UPLOAD] Produce 3 levels of synthesis: **Level 1 — TL;DR** (3 lines max): situate topic, stake, key idea. **Level 2 — Summary** (1 page): - 5-7 key concepts - Precise definitions - Concept links - 2-3 type examples - Essential formulas or rules **Level 3 — Detailed** (2-3 pages): - All course concepts, structured - Key demonstrations - Special cases and exceptions - Links with other program parts - Classic assessment traps Dense, no paraphrase, level-adapted.
Synthesis from multiple sources
For same topic [TOPIC], I have multiple sources: **Source 1 — Professor handout**: [CONTENT] **Source 2 — Reference textbook**: [CONTENT] **Source 3 — YouTube video**: [TRANSCRIPT] Produce integrated synthesis: 1. **Professor's approach**: what they emphasize, their angle 2. **Textbook contributions**: precisions, rigorous demonstrations, examples 3. **Video contributions**: intuitions, metaphors 4. **Integrated synthesis**: everything to know, simplest to most subtle 5. **Discrepancies between sources** and who to follow for assessment (professor priority)

Frequently asked questions
Is synthesizing with AI learning?
Provided you interact with synthesis: annotate, rephrase, self-test, explain to a classmate. Reading AI synthesis passively means forgetting in days. AI synthesis is a starting point, not a final deliverable for your brain.
Can AI synthesize a course video?
Yes: transcribe with NotebookLM (accepts YouTube links), Otter or Whisper, then synthesize. NotebookLM does it directly integrating the video. Very powerful for online courses (Coursera, edX, MIT OpenCourseWare).
How many pages can be synthesized at once?
With Claude or NotebookLM: easily 100-200 pages at once (1M+ context tokens). With ChatGPT: variable limits per version (often 50-100 pages max). For very large documents, split into coherent sections and synthesize in chunks.
Does AI summarize hard sciences correctly?
Well on definitions and concepts. Risks on long demonstrations (may omit critical steps) and notation (may simplify or modify). Always verify key demonstrations and formulas with official handout.
