Marking Scheme – General Instructions :
01. The marking scheme provides general guidelines to reduce
subjectivity in the marking. The answers given in the marking scheme are
Text Book , Solution Book and COME BOOK bound. The contends of he text
book, Solution Book and Come Book are thus indicative .If a student has given
any answer which is different form one given in the marking scheme, but
conveys the prescribed content meaning, Such answers should be given full
credit .
02. Evaluation should to be done strictly adhering the instruction
provided in the marking scheme in order to ensure uniformity in the
assessment of candidate’s performance .
03. In an answer to an question , between any two particular stages of
marks (greater than 1) if a student start from a stage with correct step but
reach the next stage with a wrong result then suitable credits should be given
to the correct steps instead of denying the entire marks meant of this page .
04. Only a rough sketch of the diagram is expected and full credit must
be given for such diagrams that form part and parcel of the solution of a
problem.
05. Marks should not be deducted in questions on determinants and
matrices , if arbitrary constants are assigned to variables other than those in
the marketing scheme.(The same will be applicable for sequence of
elementary transformations applying to get echelon form of a matrix).
06. Marks should be awarded for correct answers to questions on the
vector equations of lines and planes irrespective of their equivalent vector
form.
07. Marks Should not be deducted in questions on applications of
integration if the correct dimensions such as square units for area, cubic
units for volume are not specified .
08. In questions on variable separable , homogeneous , linear differential
equations of first order , full marks should be given for an equivalent answer
and student should not be penalized for not getting the final answer
mentioned in the marking scheme .
09. There is no separate mark allotted for formulae . If a particular stage
is wrong ad if the candidate writes the appropriate formula then award
suitable mark for the formula, This mark is attached with that stage .This is
done with the aim that a student who did problem correctly without writing
formula is not penalized.
Thai is mark should not be deducted foe not writing the formula.
