RPET Solved Sample paper

Well if a candidate has clear concepts regarding physics,chem and maths in 11th and 12th then one can easily crack the exam. One just need to practice for time management as some questions are lengthy or tricky so may take some time to solve.We have an excellent application for the candidates to help them prepare for the exam that is itest. Interested candidates can take an online test on RPET at itest and  can check where they stand, which will help them to improve themselves.
