Hello dear student,

If you want to appear in net exam keep few things in mind you know paper is divided into three sections first being aptitude section which comprises of mental maths questions and some reasoning questions some question related to English and you just have to solve the questions instantly it is a mental exercise kind of questions. Second and third section is all about your subject and you have to solve questions accordingly like they comes directly or indirectly from your subject only.you have to give answer of a question you think you know the answer otherwise I hope you are aware negative marking is also there. C-section is basically needs a practical approach rather than theoretical approach

I hope this is helpful to you

Best wishes and thank you
