This is a deliberate practice exercise to help you bridge the gap between the Spanish you don’t know and the Spanish you could know after spending some time in focused mode.

The three sentences below contain 10 mistakes in total.

Each mistake has a corresponding reference sentence that contains the correct usage.

You only need to do three things to get value from this exercise:

  1. Pore over the reference sentences until you think you’ve noticed their subtleties.
  2. Try your best to find the 10 mistakes in the three sentences.
  3. Match every mistake with its corresponding reference sentence.


M0: ¿Cuál es la problema?

R0: Tengo un problema.

Answer: ¿Cuál es el problema?

Post your attempt in the comments and I’ll send you the answer key.

Have fun!

Pro tips

  • The faster you finish, the less you’ll learn. Use this exercise as an excuse to slow down and get good at noticing.

  • The point is not to find all 10 mistakes; the point is to notice something you would have normally missed.

  • You can rely on your gut for the first pass, but I also encourage you to Google anything you’re not sure about (and to use spell check). If you’re confused, go back to the reference sentences.

  • You can also ask natives, but figuring it out on your own is much more satisfying (and easier to remember) than being told the right answer by someone else. However, once you’re done, feel free to check out other people’s attempts.
