much easier same as like intermediate public examinations pattern

From the tag it shows that you are asking about the mathematics of ECE Course. Let me make you clear that nearly any branch of engineering requires very strong mathematics. CSE, ECE, Mechanical are some of them. Some like Biomedical or Genetic engineering requires less of it. So if you are not good with the basics or you don't feel comfortable, then don't choose the branch which requires it. If you think you can do good maths with practice, then you may think about choosing ECE.

Thanks.
