What Can Parents Do to Help for NSO 2023-24?
We understand that not all parents might be able to help their children during their studies. Parents, after all, have their own work to do as well, so it is unreasonable to assume that everyone has the time or energy to help their children with schoolwork on top of everything else. However, there are two things that parents can do to help their children prepare for the NSO 2023-24. The first thing is to ensure that the child has not forgotten to download any of the materials they need. These materials are essentially the sample papers and the syllabus for their year. The sample papers can be found here, while the syllabus can be found here. The other thing that parents can do for their children is to make sure they are calm and relaxed. Putting too much pressure on them will cause them to explode, so it is best if the parent offers gentle encouragement and help if needed, while allowing the child to study for the exam at their own pace. Make sure they are taking enough breaks for meals and leisure time as well!
