Hello!
Unfortunately, I can not give any valid criticism about the courses themselves, but regarding the advertising brochure I have the following comments:
1) What did I just look? Interracial porn? Trying to please all nationalities, looks, uh ... I do not know. Torn me away from the product.
2) My God! In the block "BLOCKHAIN TECHNOLOGY" is really insertion from the code of assembler? Any IT specialist will laugh at the voice.
That's all I wanted to say.

May the Force be with you
