**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.01. The marking scheme provides general guidelines to reduce
