Year in, year out our secondary school students fail their O\'level and Jamb exams, So at the samsung developer's challenge going on right now in Nigeria, I developed a phone application to save our secondary school students from frustration and failure. The name of the application is PRUDENT Student\'s Companion developed with the aim of helping senior secondary school students (science students) to boost their academic performance by teaching the rudiments of science subjects. PRUDENT contains a Mobile Laboratory that brings the lab experience right into your hands, Classroom aids which include the periodic table, the whole human systems (explained and illustrated), formulas in physics, and physical constants. Infact right now the application (PRUDENT) is in the final stage of the contest where Nigerians are expected to go to the site www.samsungnigeriaappscontest.com, register and then log in to rate and download the applications. I hope a number of Nigerians rate and download PRUDENT and share it to our student's who need it. THANKS
