Study from a PDF

A PDF is usually a container, not a study system. It holds material, but it does not tell you what depends on what, what you already understand, or what needs another round of practice.

BaseHalf turns the PDF into a Map so the material can be opened, edited, connected, and reviewed.

Upload the source

Attach the PDF and describe the outcome you want.

Split this PDF into study spaces.
Keep definitions, examples, open questions,
and review tasks separate.

This gives BaseHalf a clear target. You are not asking for a one-page summary. You are asking for a reusable learning surface.

Add the purpose if you know it. Studying for an exam, preparing for a seminar, writing a literature review, and teaching the material all require different structures.

For example:

Split this paper into study spaces for a seminar discussion.
Keep the thesis, evidence, assumptions, objections, and discussion questions separate.

This helps BaseHalf create Points that match the job, not just the document outline.

Create study Points

The first Map should separate the material by purpose:

• Source overview for the document's main argument or lecture structure.
• Definitions for terms that must be remembered precisely.
• Examples for concrete applications.
• Open questions for material that is still unclear.
• Practice tasks for recall, explanation, and problem solving.
• Review plan for what to revisit next.

This matters because each category needs a different kind of follow-up. A definition needs precision. An example needs transfer. An open question needs explanation. A practice task needs feedback.

Open weak areas

When you find a weak area, open the relevant Point instead of asking a new general question.

Inside the Point, ask BaseHalf to explain the concept, generate examples, compare it with nearby ideas, or turn it into practice questions. The work stays attached to the Map, so the study system improves as you learn.

The Point title should name the weakness. Chapter 3 notes is not as useful as Why the author separates attention from memory. The second title tells you what kind of understanding is missing.

When a weak area becomes clear, keep the better explanation as a Block inside the Point. That explanation can later guide practice questions, a presentation outline, or a comparison with another source.

Link evidence to understanding

If a summary depends on a passage from the PDF, reference the source Point. If a practice task depends on a definition, reference the definition Point. If an open question is answered later, reference the answer back to the question.

These links keep the learning surface honest. You can see which claims came from the source and which parts need more review.

Review by changing the Map

Studying is not only reading. It is updating the structure of what you know.

After each review session, move or revise Points:

• Merge duplicates.
• Split overloaded Points.
• Mark decisions or answers that are now stable.
• Turn weak concepts into new practice tasks.
• Keep the next review step visible.

The PDF stays as the source, but the Map becomes the system you actually study from.

What to delete from a study Map

Do not keep every extracted sentence. A study Map should contain the material that changes understanding.

Remove or merge:

• highlights that do not support a claim
• summaries that repeat the PDF heading
• practice questions that test the same recall
• open questions that were answered elsewhere
• definitions that are too broad to be useful

The goal is not to reproduce the PDF in another format. The goal is to create a system that makes the next review sharper.
