Separate knowledge from physical performance
A video can explain a concept, while performing a delicate operation requires a suitable environment and feedback. List the skills you want to learn and mark which involve reading, reasoning, physical handling or live observation.
Ask how feedback actually works
For each format, ask whether an instructor reviews your measurements, watches practical technique and corrects errors. A recorded demonstration and supervised student practice are different experiences. Confirm equipment access and permitted practice material rather than assuming they are included.
Choose an arrangement you can verify
Compare an example lesson and assessment where available. If the course blends formats, ask which tasks happen in each setting. Avoid treating a completion badge as evidence that a physical repair skill was assessed. The useful choice is the format that supports your learning task, schedule and required supervision.
The course only shows recorded demonstrations
Ask how your own work is reviewed and what practical facilities are required. A clear explanation of a process is useful, but it does not establish that your physical technique has been assessed. Confirm the gap before deciding the format suits your goal.
Your practice record
- Skills divided by type
- Feedback method confirmed
- Practical access and equipment
- Assessment matches the claimed skill
Repair procedures involve heat, electricity, fragile parts and customer data. Practise under qualified supervision and work only on devices you are authorized to service.
