Hey guys, i am currently studying engineering of information technology and i must say i am so f***ing lazy! i am now in the 2nd semester but i didn't write the exams for the first semester because i was too lazy to learn so i will have to write them later. i am looking for a program or app or something else which can help me in maths, physics and electrical engineering! i have seen a nice app on android market but it cost money and still did not found it for free in the net. so maybe there are ppl who also study this kind of enigeerring and use programs thanks in advance!
