Hello toasters!
Please share experience.
1. How is the exam organized?
2. Is it difficult?
3. Who prepared how?
4. Did you find answers to questions (or at least a list of questions)? I searched - I find only information products on-demand.
5. Where did you take it?
6. Are there any discounts, promotions for the purchase of vouchers?
I and many other people will be grateful for the information - after all, the question is unique.
