Hey,

You need not worry about the same. There will be no difference in level of questions asked in the examination. You just need to be well acquainted with solving the entrance exam questions on the computer. For improving this, you can better perform mocks tests available online specially in the computer based type. Relax as nervousness can really result in forgetting the concepts. Leave this thing out of your mind that CBT will have tougher questions as compared to offline mode. Revise daily and solve mock papers to ace the exam.

Hope it helps.
