Note : The prime purpose of the post is better presentation. Answers in the actual board’s answer key may be different.

Some parts of the presentation are totally not required but if possible and if time permits, it is better we do.

Not so required parts are :

  1. Writing the questions. (It is better to write because the examiner won’t have to look in the question paper back and again, reducing his/her efforts setting a good impression on her)
  2. Leaving lines after question/points. (Better to leave because then the paper looks neat and spaciously written even if handwriting is not so good)
  3. Reasons/Correct statement for true or false, odd man out, etc. (It was compulsory before, but not now unless it is mentioned so. However, if you know precisely better to write to show your knowledge).
  4. Extra points when the number of points is specified. e.g. Q. 2 (4),(5) (They won’t fetch you extra marks, But if by chance, one of the previous points is wrong/incomplete; then this extra point will be considered)
  5. Title for each answer and boxing it. (However, doing so will reduce the efforts of the examiner to read the questions. If you do this, it will be fine even if you don’t write the questions.)
  6. Writing examples for Differentiate between (note: Examples are not considered as point for Differentiate and hence won’t be given marks)
  7. Writing reasons like ‘Subtracting/Adding’ in numerical questions. However, reasons like ‘Substituting/Invertendo’ are must.
  8. Drawing border around diagrams. Shading in diagrams.(However, it is better to draw because your diagram will seem to be more neat)
  9. In IUPAC naming, first giving the details like no. of atoms, root word, f. group. It is OK if you don’t write that part and directly write the IUPAC name; but writing that part makes your work easier as while writing the IUPAC name, you just have to combine that all. Basically, it’s type of mathematical.
  10. Writing main questions like ‘Attempt any 5 out of 6’, etc. (Totally not required, but see that the question no. is correctly written)
  11. Writing a long explanation for reactions. (writing so takes the examiner directly to laboratory virtually and do it’s good to do it).
  12. Drawing the border lines and lines between the answers. (Better to draw because your paper looks neater.)

Please Note: In Answer to Q. 3 (2) on page 13, due to unavoidable circumstances, I have written even below the last line of the page. Please don’t that in examinations, even I haven’t done that in other rewritten answer papers. It is always advisable not to write on and after the last line as well as on or before the first one. Again, apologies for the same.
