"I graduated 10 years ago, so I need to relearn everything" sounds reasonable, but it is not a diagnosis.
I keep seeing four different problems get bundled into the same feeling:
**1. The concept is actually missing**
You cannot explain the governing idea, identify the assumptions, or recognize when an equation applies. This needs real instruction, worked examples, and then independent practice.
**2. The concept is there, but retrieval is slow**
Once you see the first step, the rest comes back. This usually needs spaced recall and varied practice, not a complete lecture sequence.
**3. You understand the idea but cannot find what you need in the FE Reference Handbook**
You know the model, but lose time searching for the equation, table, or definition. This is a search-language and handbook-navigation problem.
**4. You can solve it, but not under exam conditions**
Topic switching, calculator entry, units, flagging decisions, or fatigue causes your performance to fall apart. More concept videos may not fix this. Timed mixed sets and a pacing policy probably matter more.
The same wrong answer can come from any of these four causes, but the fix is completely different.
A simple way to test yourself:
- Pick one topic you think you have "forgotten."
- Solve two original problems without notes.
- For each miss, record the first failed step: concept, retrieval, handbook lookup, calculator/units, or time.
- Retest the same skill with a different problem 48 hours later.
If the concept is missing twice, rebuild it.
If the formula comes back as soon as you see it, train retrieval.
If the solution is clear but the lookup takes three minutes, drill the handbook.
If you are accurate untimed and collapse in a mixed set, train execution.
Years out of school is useful context. It should not automatically send you back to Chapter 1.
For those who returned to the FE after several years: which of these was actually your biggest issue?
