This is an Ielts admission center. The center itself is good and everything is well organized, polite staff and full provision for everything. But you won't get a normal score anyway. I have been preparing for a long time and I have made significant progress - I felt it myself and the trial in Moscow confirmed that I can get 7.0 in general and in all components and I have recently received CAE. I get 6.5 - b2 on their exam.
Speaking has never been lower than 7.0 for me - they have 6.5, and they put 5.5 for writing (everything was divided into paragraphs and with an oaeray and added a sentence topic (in Kazakhstan there was 6.0 without a sentence topic, there was also a total score of 6.5). I think it's useless to take Ielts in Yerevan and Astana in such a situation, or it was only me who had such a biased attitude. I don't know. Try to pass, you may be lucky, but it's better if finances allow you to go to London.
My son took IELTS here. A very cozy educational center with very friendly staff. They tell you everything in detail. Water, coffee, sweets, cookies are free.
