My 4 years of Excel training i have handled variety of projects, each different from one another, as client requirements will be different in Excel.I would like to say you about a government project i handled and completed recently. This project was for underprivileged students who had no proper communication but wanted to learn Excel.So my first challenge was to make them properly speak and understand English.After this, things went on , but with lot of difficulties as the students mainly were college dropouts, i had to repeat things very often to make them properly understand the concepts.At the end when the training was over , i was very much happy as almost 90% of the students had got placed in good companies, this gives me a tremendous feeling of success and i was happy for my students , that they learnt Excel properly and got placed in good companies.
