Welcome to the Interactivities! We have four sections in interactivities:

Multiple choice questions
There will be 15 multiple choice questions for you to answer. And these questions are selected at random from a bigger set. So the next time you want to attempt the quiz, you might be presented with altogether different questions!
Scrambled Words
Try your knowledge at these scrambled words. You will be given a scrambled set of letters and a clue for the word. Try guessing the answer from the letters. And if it's too tough for you, just hold the mouse over the set of letters...


Send your queries to us. And we shall try to solve your doubts. But please stick to the topic of ...trailing the Transistor. And we also recommend that you try our Learners' Center to see if the Message Board can help solve your doubts.
