A little math to properly allocate and save your money:
110 hours of classroom work are waiting for you at the price of 25 000 UAH.
So, you only pay 228 UAH per hour.
And this is a real price explosion.
And this offer is valid only in our training center.
Now it is reasonable to be not only cool, but also profitable!
