How To Learn Really Difficult Subjects (By a Straight A Engineering Student)

Main ideas / concepts

• Studying difficult subjects is learnable (not inherently “hard”)

  • A subject’s difficulty depends on perspective. Students may label something difficult, but others can perform extremely well.
  • Reframe the mindset:
    • Instead of “this subject is difficult,” think “this subject is challenging.”
    • Believing a topic is hard can create stress/resistance, which blocks learning.
  • “Difficult” subjects mainly require different approaches and may take more time, but are fundamentally learnable.

• Why difficult subjects feel overwhelming

  • They heavily tax working memory due to:
    • difficult concepts
    • lots of memorization
  • At the start, seeing lecture slides (formulas/diagrams) may trigger fear/confusion, but this normal “overwhelm” tends to fade with repetition and tactics.

• Brain as a learning machine

  • The speaker compares the brain to a machine designed to learn: with the right inputs (methods/tactics), it can learn effectively.

• The “nature of difficulty”: what makes subjects hard

  • Three main sources of difficulty:
    1. Lots to memorize (example: medicine)
    2. Lots of procedures / skill-based practice (example: math)
    3. High abstraction / hard-to-visualize concepts (example: linear algebra / many dimensions)

• Core methodology to learn difficult subjects

  • Use three principles:

    1. Time (spaced over days)

       • Emphasis on spaced repetition, not cramming.
       • Analogy: listening to a song daily for ~2 weeks leads to memorization/performance.
       • Practical approach: short, repeatable study bursts (e.g., ~20 minutes) done every day.

    2. Repetition

       • Revisit material after breaks (spaced repetition).
       • More time/reps generally improves mastery.

    3. Methods (use evidence-based techniques—especially active recall)

       • Active recall = test yourself and retrieve information from your mind rather than rereading.
       • If the topic requires memorization, build a bank of self-made questions and repeatedly test those concepts.
       • The speaker’s university strategy:
         • reading lecture slides
         • frequently testing themselves via questions

• Managing cognitive strain and learning efficiently

  • Use short bursts + breaks to avoid overload.
  • The speaker references a book (“A Mind for Numbers”) describing two learning modes:
    • Concentrated mode (focused problem-solving)
    • Diffuse mode (stepping away to let the brain reset/process)
  • Break ideas:
    • walking outdoors/nature (e.g., birds/trees)
    • shower
    • being away from the phone
  • Work in chunks:
    • alternate between small sets of concepts, returning to them
  • Always keep fundamentals solid:
    • getting stuck in advanced material is often due to missing basics from earlier weeks/topics
    • example: understand trig formulas deeply (how they’re derived/created), not only brute memorization

• Why this skill matters in the future

  • Learning difficult subjects is portrayed as a rare but valuable skill in a world with rapid change (example: AI).
  • The advantage is the ability to learn new things quickly.
  • Personal motivation/theme:
    • the speaker initially pursued engineering partly to seem impressive
    • later, they found lasting value in learning difficult material

Methodology / instruction list (detailed bullets)

Step 1: Change your mindset about difficulty

• Ignore what other students say about difficulty (it’s perspective-dependent).
• Reframe:
  • “This subject is difficult” → “This subject is challenging.”
• Avoid stress loops caused by predictions like “people fail it / I’ll fail too.”

Step 2: Identify what kind of difficulty you’re facing

• Determine which category the subject mostly falls into:
  • Memorization-heavy → plan for recall practice
  • Procedure/skill-heavy → plan for repeated problem practice
  • Abstract/visualization-heavy → plan for conceptual grounding and iterative understanding

Step 3: Apply the “3 principles” for learning difficult subjects

• Time

  • Study using spaced repetition (learn → break → learn → break → learn).
  • Prefer short daily sessions over weekend cramming.
  • Example rhythm:
    • ~20 minutes study
    • take a break
    • repeat later the same day or next day

• Repetition

  • Re-encounter material across multiple days to strengthen recall.

• Methods

  • Use active recall:
    • close the material mentally and retrieve information by self-testing
    • don’t rely mainly on rereading
  • For memorization-heavy content:
    • create your own question bank
    • repeatedly test those questions/concepts
  • For lecture-based courses:
    • read slides/material
    • immediately test yourself on what you just read

Step 4: Expect overwhelm at the beginning and push through it

• Treat early confusion as normal.
• Keep studying despite fear/uncertainty—mastery grows as patterns become familiar.

Step 5: Manage working memory strain while studying

• Use short bursts (example: 20 minutes) followed by breaks.
• Add diffuse-mode breaks:
  • walk in nature, shower, etc. (avoid phone time)
• Study in chunks:
  • focus on one concept/topic briefly
  • switch to another
  • return back and continue cycling

Step 6: Never skip fundamentals

• If you feel stuck in advanced concepts:
  • check earlier fundamentals (from old units or early weeks)
  • fix gaps before continuing
• Aim for understanding how ideas work (derivations/creation of formulas), not just memorizing formulas.

Step 7: Build the long-term benefit

• Keep practicing difficult-subject learning because it builds a transferable skill: learning hard things fast, which becomes an advantage in a changing technological world.
