Hi Oleh,
let's go through the exam topics list:

  1. Buffer and Streams – 11%
  2. Control flow – 12%
  3. Child Processes – 8%
  4. Diagnostics – 6%
  5. Error Handling – 8%
  6. Node.js CLI – 4%
  7. Events – 11%
  8. File System – 8%
  9. JavaScript Prerequisites – 7%
  10. Module system – 7%
  11. Process/Operating System – 6%
  12. Package.json – 6%
  13. Unit Testing – 6%

I assume you have a good knowledge of Javascript, asynchronous flow, events. You also test your code. If I'm right, the topics: 2, 5, 9 and 13 shouldn't be a problem. If you work with modern technologies and use npm to install dependencies you should already know 12.

4, 6, 7 are quite easy. In my opinion the biggest challenge for a frontend dev are 1, 3 and 8.

Of course it's hard to say how much time you need, it depends on your experience...
