Note-taking cho academic lecture — sơ đồ branching cho Section 4

Vấn đề với linear notes

Ghi linear từng câu trong Section 4 → bạn rớt sau 30 giây vì speaker quá nhanh. Cần hệ thống ghi efficient.

Hierarchical note-taking system

Setup trước khi nghe

Đọc câu hỏi → identify structure:

• Có 10 blanks consecutive → expect chronological process
• Blanks chia 3 groups → expect 3 sub-topics
• Có table → expect comparative info

Symbols rút gọn

• → = leads to / causes
• ∴ = therefore
• vs = contrast
• e.g. = example follows
• & = and
• + = additionally
• # = number/figure
• ↑ = increase, ↓ = decrease
• w/ = with, w/o = without

Branching layout

Thay vì viết linear:

Climate change causes drought
Drought leads to crop failure
Crop failure means food shortage

Dùng branching:

Climate change
  → drought
     → crop failure
        → food shortage
