The Kolkata-lad finished second in his category but his score of six-under 210 also got him a fourth spot in the overall tournament.
Playing against 90 golfers from 18 countries, Madappa played his heart out but lost to the eventual winner Simon Zach from Czech Republic by three strokes.
It was Madappada's first outing at this R&A world amateur golf ranking event, as he had to miss it twice owing to his academic examinations.
The 17-year-old Madappa expressed disappointment on missing out on an opportunity to play in an Asian Tour event, an incentive for the winner.
"It was amazing just to be in the same room as Sir Nick Faldo. To have an interaction with one of the greatest golfers was just mind-boggling," added Madappa.
Other Indian participants who put up a spirited show were Patna's Aman Raj and Delhi's Shubham Narain. Raj finished fourth with a total of one-under 215 in U-21 category while Narain ended the tourney in ninth position at five-over 221.
