HELLO!!!Students …. Lets Learn something New….

• General Instruction• Read the learning material thoroughly .

• Whenever required take an quick recap of the paragraph .• Try to solve all the questions.• Answers one Question at a time.• Whenever feel difficulty , go to the content part.• Wherever audio or video given, observe them thoroughly. So that you can properly

able to answer the Questions given.

Lets start!!!
