Detect Vehicle Problems
When your car is acting up or breaks down, the last thing you need is a communication breakdown with your technician. Learn how to describe certain sounds with Lesson in sounds: around the vehicle or Lesson in sounds: under the hood. Get an idea of what the leak spots on your driveway might mean in Lesson in liquids. Then next time you make a trip to the repair shop, you and your technician will be talking the same language.
