yes, it is the best time of career when you can start with projects. study j.b.gupta analog electronics book for complete concept of transistor and components as well as circuit theory of A.k chakraborty. then start making circuits to glow leds,buzzer buzzing,firealarm. surf the net for circuits concept but calculate yourself different values of components because 99% designs given on net dont work. first learn to make basic circuits then you can move on to advanced circuits. and for any query further you can contact in this forum.
