    Hi Friends,

                    This s Kaarthik kumar from Hindusthan College of Engineering & Technology, Coimbatore. This CSC preparation guide is more than enough to get into CSC. If not possible to go thru d entire page, ATLEAST GO THRU D TECHNICAL WRITTTEN SECTION!

    CSC has got 5 rounds to go through

    ·         Aptitude written

    ·         Technical Written & Essay

    ·         GD/JAM

    ·         Technical HR

    ·         Personal HR


                    R.s AGGARWAL Book is more than enough to clear this round. So keep practicing mainly on following areas

    • Averages &Percentages
    • Profit & loss
    • Ratios & Ages
    • Time & Distance
    • Probability n combinations
    • Analogies
    • Sudoku type


    1)There are 3 piles of books on the table you need to arrange them in the self such that 1st book of each pile gets placed on the self,what is the possible no of arrangements:
    a)12!    b)12C3 * 9C4 c)12^12 d)none

    2)Price of a book increases 15% successively (2times) what is the new price of the book more compared to that of the old price:
    a)32.25%    b)23.34%    c)36%    d)39%

    3)There are 3 mixtures when mixed in the ratio of 3:4:5 price was 240.When mixed with 6:4:9 price was 340.what's the price when mixed in 5:6:8 ration price is_________

    4)One question based on Venn Diagram.75 total no of students.25 don't know typing,50 know shorthand.then question were based on find no of students dont knwing both etc.

    5)One person has 2 child.At least one of them was a girl.Then the Probability that 2 of the are girl is_____

    6)Swati when get married to jayanta her age was 3/4 th of her husband's age.After 12 years her age became 5/6 th of her husband's age.Then what's the age of swati when she got married??

    then what's the value of y???

    8)some passages were there based on illegal drugs smuggling and based on this some questions.

    9)Some Analogy Questions: some i do remeber like SYCOPHANTIC: FLATTER SILENT: QUIET others i dont remember.

    10)Some questions based on
    if  f(x,0)=x+1

    then find f(1,1),f(2,3),f(3,0) etc and some relations based on this very easy
    11)One question based on the average speed
    12)one question based on Sudoku type very easy,u can do it in one attempt




    1. Sudoku. you need to fill-up the table using the hint(addition of row, column, diagonal =15) and available cell values. its easy. if you figure it out, you can answer(very easy)
    five questions correctly.
    2.If y=MAX((3x+y),(11x-y)) then what's the value of y?
    3.1 Que. on book arrangement. if u find out the series you can ans five ques. correctly.
    4.2 Ques. on Probability, ages
    5. Ages
    6. Venn diagram --> Out of 100 students, 45 do not know typing, 60 know shorthand. 25 know both 6 do not know anything then find out haw many know both?
    7. if  f(y,0)=y+1, f(o,x)=x; f(y,x)=f(f(y,0),f(2*y-1))  then find f(1,1),f(2,3),f(3,0); 3 question based on this. Its very very simple...
    8. 1 Ques on Percentage : Price of a book increases 15% successively (2times) what is the new price of the book more compared to that of the old price:

    indentify which is a dancer which a singer.....


    2 ques on...dere r 3 frens nd dey hv sum marbles wid x gives to y nd z amount of marbles

    which dey already hv...nd den z gives 2 x nd y amount of marbles which dey already dey

    hv equal no. of marbles...also total no. of marbles was given...u hv 2 make equations nd solve dis ques






     1.  A 3*3 blck is given and should be filled frm 1...9 they gave 3 numbers nd when coundted horizontally,vertically and diagnally they should sum 15. they gave nearly 7 questions on this blk really easy if u practice sudoku.

          2. If x,y are 2 positive integers and they are derived as follows:
              then wats the value of f(3,0),f(1,2) etc nd hw f(1,2) can be derived in terms f(0,0),f(0,2),f(3,0)
                   there 5 questions relating to this.
         3. 1question on ages i dont properly remember the questions
         4.7 questions on anlogy,fill in the blanks
         5.deriving conclusions 10 questions


    it was a very tough test i hav given test of 6-7 companies but csc test was toughest
    ther vr linear equations questions wich vr not at all easy
    questions on sets
    -permutaion combination
    -arrangement logical ques
    - distance speed ques
    - time question

    -ques like 90% of 1 litree milk and 60% of 40 litre water result in 67% mixture so wht is compostion of milk in litres?

    -ques like f has pririty over h and g has priortiy over i so now 4-5 ques based on this

    -length is increased by 5 and breadth is decreased ny 10 thn total is 200m and whn length decreasd by 5 and breadth increasd by 15 thn total is 75 m, fing length

    -a>b>c so wich is tru
    ab>ac or a/b>b/c or som more options

    -6 girls and 6 boys, all boys and all girls will sit together so no of possible ways

    - cow is tied with rope from two sides 40 40 cm and forming an angle 24degree size of rope is 15cm so how much area in wich cow can graze

    -7 orange and 5 apples cost 16.90 rs and 5 oranges and 7 apples cost 2.60 so no of oranges

    -ther is a place wher ppl r either no or yes. if ram sain 2and 2 makes four thn he is yes and similarly if mohan said 2 -1 is 2 thn he is no. so now ques based on this

    - paragraph given and u hav to conlude or find contradicting line

    and rest all questions vr very tough so i dont remember thm at all

    This is the main round of elimination. Don?t  get afraid But be prepared.

    A group of 10 members will be called and given a topic. On a random order u?ll be called to speak individually for 2 mins. Don?t worry the moderator wont even look at u. he?ll keep listening to ur speech thru his ears. They mainly expect how confident r u expressing from ur mind without fear. So drive out fear completely. The other factors a pronunciation n clarity (without stammering).

    ?Wat u speak doesn?t matter But How u speak Matters a lot in GD/JAM?

    Few Sample Topics:

      • My worst vacation
      • We all make mistakes
      • The most unforgettable Dream
      • External outfit
      • What do I fear for?
      • The first day of my college
      • My seniors in college


    Be confident in this round. They mainly check how confident r u in answering. If u get thru this u r almost selected.

    Prepare to be ready to answer

    • About ur project
    • C & C++ (even they will ask u write programs)
    • Any question from ur area of interest. (DBMS & DS have more advantage than OS/Networks)
    • Basics in all subjects


    H.R-primary key n foreign key multithreading and multiprograming
    After that she had given me some puzzel.
    there are 3 boxes in 1st contain red ball,in 2nd white,3rd mixture of white n red in how many attempt u will find out which box have which color of ball.
    cut a cube in to 27 equal pieces and if all side of cube is painted then how many piece of cube remain unpainted in 27 pieces of cube.

    Then asked me about the Logic of Prime no,Bubble sorting,linked list,merge sort etc.(Basics),One logic based on the odd no i don't remember exactly.


    1) whn u open web browser, thn wht will happen wht do u do first thing?
    2) wht u write first thing, i said DNS or webaddress concept thtn he asked complete web adress like i told
    thn he asked meaning of each word-http,www,com etc
    3) wht is URL
    4) tel complete procedure how a site open after opening explorer
    5) other layers understand DNS or not if not thn wht will happen (concept of mapping to ip adress comes here) thy asked how mapping takes place and at wich layer
    6) dns procedure use wht tcp/ip or osi
    7) how many layers in tcp/ip and wich layers are extra in osi model
    8) tcp/ip conection oriented or conectionless
    9) wht is DNs he was trying to ask in detail but as i havnot read so i said tht
    10) wht is arp
    11) wht is rarp
    12) wht is ATM(asynchronous mode transfer) 

    1) wht is primary key
    2) if ther is no primary key how will u uniquely identify each tuple (i said composite key or super key)
    3) diff between tuple and attribute
    4) wht r anomalies explain each in detail (like insertion anomaly deletion and modification anomaly)
    5) wht is foreign key constraint
    6) if i want to delete a tuple from a table having reference in so other table thn wht will happen (concept of cascade comes else error)
    7) wht r triggers explain
    8) if i want to hav som tuples havind null value wht to do (outer join)
    9) wht if i join two tables and no primary key (spurious tuples generate redundant data)
    10) he asked me wht will u do if need to retrieve this so basically query
    and select first four tuples
    select *
    from employee
    where salary
    thn apply rownum<=4 to select first four tuples
    11) diff betweenoracle 9i and oracle 8
    12) diff between dbms, rdbms, ordbms 

    1) wht is os
    2) wht is a process
    3) diff between process and thread
    4) if threads share data section wht will happen
    (concept of semaphore and crtitcal section comes so )
    5) wht is semaphore
    6) wht other thing semaphore do except synchronisation
    7) wht else happen in threads and process so deadlock concept comes
    8) deadlocks, and i told abt 4 conditons of deadlocks also
    9) in os wher do u use stacks and queues
    (like stacks for saving process satate , on system call context switch etc and queue in scheduling so he asked do we hav only fifo scheduling)
    10) so types of scheduling 

    Data Structure
    1) u hav fifteen boxes in kitchen and ur mom asked u to make foos for 1 month, wht will u do to make food fast (thn concept of sorting came)
    i said i will put name tag on boxes and thn sort thm in ascending order or i can put thm in order of color shade firstly lightest and thn little darker and soon but tht can create confusion so first is better way
    2)u hav 1000 names in unorder manner and i asked u to pick any name of my choice randomly and thn giv me complete info of tht person so wht ds will u use
    i said firstly i will sort thm thn i will use hashing/btrees as thy r faster in decreasing search domain,
    thy asked wich sort will u use
    i said radix as good for strings , he asked if one more name increase or decrease i said radix sort take linear time so doesnot affect much on time
    he said if names r vary in length like one is venkateshraman other is raj i said sort from 3rd last letter or use padding.
    3) wht is heapsort, concept . wher u can apply it
    4) wht all ds u know
    i said heaps binomial fiboncaai, liked list stacks queues trees arrays etc
    5) advantage and disadvantage of linked list and array over each other in temrs of memory allocation
    6) insert and delete a node in a linked list write a code(not from me)

    basically thy asked asll application based question on data structure 

    1) write a java code of swapping to name via calling object as parameter and asked whther result will reflect in main or not
    (as object passed as a reference so reuslt will be reflected)
    2) in java we use call by reference or call by value
    3) wht r interfaces
    4) diff between interfaces and abstraction
