Dear Sir, I have placed order with your Institute for material for promotions to Officer cadre. I am very happy to inform you that with the help of your material I cleared JAIIB in the very first attempt followed by passing CAIIB in the first attempt in the very next half year. This has been possible because of excellent material provided by your Institute. I am sure that I will come out successful in the promotion test also with the help of your very valuable material. With best regards.
