High School Science: Chemistry Part I: A Practice Book for High School Students

For Students

We expect a kind of understanding from students of Grade 10 to 12 of the National Curriculum. The fellow student should understand the number system and related operations. There are some relationships exist in between number systems of various types. We often come across four different number system in computer Science. For the class works and mathematical operations of Grade 4 we restrict our discussion to decimal system only.

I hope the kind of effort and combination of problems might enhance the knowledge base of our fellow students.

For Parents

Questions are there without respective answers. It can be obtained from the source. There exists a plan of fulfilling dual purpose of the effort. These sets can be utilized to engage a student for working out the possible outputs without being inflicted primarily with answers.

If answers are provided alongside the questions then the material will fulfill half of the purpose. It cannot contingent for overcoming the problems and also cannot facilitate in skill enhancement efforts.

Set of questions can be used for the purpose of assessing skill acquisition process and also can be assigned to the ward by parents and guides.

It is not mandatory to go through all sets of problems, but not to skip any of the problems is recommended for assuring the perfect skill acquisition.
