tender age makes impact in our whole life 2 growing trees taking care of them recycling home waste harvesting rain water using solar power must be part of all housing and official buildings and societies 3 we must use renewable sources of energy 4 effective waste management at the industrial level which is major source of pollution is very important 5 we must have strict laws to protect our climate q how has this competition shaped you what have you learnt from it last year when i went for the international astronomy olympiad where i won a silver medal i was very shy and did not interact much with others but here at brazil i made lots of friends i am now more comfortable to initiate a conversation even with an unknown person the whole event schedule was very hectic but i could sail through easily as i like the subject so i learnt that if we make our hobbies our work we will never have to work and the whole life would be fun also the final competition is really tough as some east asian countries have prepared for 2 years whereas in india we only study for 3 months but with a calm mind and some optimism i managed to win as the questions were application based so i learnt that how we manage situations is more important than the preparation q can a mediocre student do well in this competition there are various international olympiads like linguistics philosophy informatics besides regular science olympiads so if student selects an olympiad based on hisher interest and is ready to invest time and to put in lots of effort it is not impossible for anyone to succeed as these are some subjects that not many people are familiar with q what do you want to become i love astronomy computers and physics but i havent yet figured out in which field i would like to go ahead i would probably be taking a combination of all three
