B.Sc

Don't worry about what happened and ask her to try to clear the subjects. maths and physics are the only two subjects she is facing difficulty to pass. There is a simple solution to get rid out of this problem i.e; ask her to prepare a schedule for studying maths and physics in a way that she has to complete the total topics with in three days. It is enough if she read all the concepts, it is not necessary to study in depth because she need to pass not need of knowing everything related to that because she is going to CSE domain not maths and physics domain. So it is better to study physics concepts and ask her to relate those concepts with practical examples such that she can able to remember them easily and she can write on her own in exam. There is no need of writing the lines that as same as in text books in the exam. Coming to maths it is better to known the concept because if she has experienced a new question other than she studied, if she knows the concept she can attempt it and will have maximum chances to get marks for that answer. In that way she can clear those subjects and there is no need of starting the course again because she will lose more three to four years again for studies. Ask her to try to clear subjects and go for further studies in computer science domain which will help her to gain more knowledge and she can get better job opportunities based on her performance in that field. All the best to you as well as your sister!
