    • Sir suppose we are applying for technical but if we failed in ekt but we qualify the 2 hr afcat paper….so will they call us for ground duty or flying … ??? We didnt passed ekt but we qualified the main afcat paper…??

  • what about those who are pursuing degree in mechanical engineering…what is the ..syllabus for them in EKT so as to get into aeronautical engineering (mechanical)

    • Yes you are, select computer science while applying for AFCAT. Once you clear AFCAT and EKT exam, you will be called for 5 days AFSB interview by Indian Air Force.

  • Sir, I am a third year electronics and communications engineering student. I have more knowledge of Computers subjects when compared to electronics subject. Can I appear for Computers EKT? will it affect me anyhow?

  • hello, i want to take afcat course from but i want to ask whether u would provide with ekt study material or not?

  • Sir, is it mandatory to appear for both afcat and ekt, if applied?
    Will i be rejected if i dont appear for ekt or failed to clear it?

  • Sir,is EKT there in on going AFSB who has cleared the AFCAT1/2014 I mean during SSB or it is only for AFCAT2/2014?

  • sir i am a B.E aeronauical .what will the syllabus for Ekt for it the same as for mechanical engineers or something different .have applied for AE(MECHANICAL)

  • Hi i am a mechanical have applied for afcat 2…please stell me the syllabus for the same as the exam is nearing and there is yet no correct information regarding the syllabus..kindly reply

  • Plzzz clarify this doubt like what if i cleared afcat and failed in ekt ??
    Is there a chance of considering me in ground duty ???

  • Sir i am a civil engineering student so plz tell in which subject my ekt exam will be conducted…as of now i have applied for mechanical as the syllbus is some what similar to our branch..

  • Hi Sir, I am looking for a book from where I can prepare for EKT – Computer Science. Can you please help with names of such books?

  • i have chosen ekt subject computer by mistake,
    i am from electronics and communication engineering,
    from above mentoned that there is computer and electonics but in my case its just computer ,
    does this effect my exam

  • Sir, is it mandatory to appear for both afcat and ekt, if applied?
    Will i be rejected if i dont appear for ekt or failed to clear it?

  • will there be SECTIONAL CUT OFF ?? means do we need to qualify both EKT and AFCAT…or combined marks will be counted ??

  • @ssb crack ….kya hai yaar kyu galat info de raha h aspirants ko …???
    we cant select ekt subject as per our wish … !!!!

  • sir iam an electrical engineer nd i have entered the details correctly and all of my frnds got their ekt subject as electrcal and instrumentation … and i got ekt subject as computer…. can i chnge this

  • sir iam an electrical engineer nd i have entered the details correctly and all of my frnds got their ekt subject as electrcal and instrumentation … and i got ekt subject as computer…. can i chnge subject

  • Sir, I have choosed my EKT as computer but i am from electrical department….i am confident to ryt d xam…is dr any restriction dat a person from only CSE has to choose computer as EKT ??

  • sir
    how the cutt of will be considered for afcat and ekt test both exam held back to back one after another on 31st agust

    either sepratly or aggrigate of both?

  • Sir if ekt paper is not clear but the first paper cut off is clear is there any chance for the call of ssb

    • Yes, there will be different paper wise cut off for AFCAT and EKT and an overall[combined scored] cut-off for technical candidates, so a technical candidate will have to get minimum cut off marks in both EKT and AFCAT general paper as well as get minimum overall score for technical branch.

    • 100 marks in EKT is really good but your AFCAT mark [115] is on the lower side. Last years AFCAT cut off was 127, so you may have a little problem there.

  • i got 136 in afcat result..and 42 in ekt
    i opted only technical field. i was unable to select the rest of my preferences
    am i selected ?

    • You should obtain cut off in both exams to get called for the technical branch. Cut off in AFCAT EKT is 45. Since you have not selected for rest of the branches, you will not be getting a call letter.

  • Sir,I’ve got 150 in AFCAT but couldn’t clear EKT. My status is : Selected. I had selected flying,logistics and admn in respective orders.So now I am eligible for Logistics and administration and not for flying,right? One more thing,I accidently filled my AFSB centre “Gandhinagar”. Can I change it somehow?

    • 45 marks is the cut off for EKT and you have got 44,so you won’t be considered or called for Technical Branch. You have 124 marks in AFCAT while the cut off is 123 AFCAT so you will be called for SSB provided you have selected other branches[non-technical] while filling up the AFCAT 2014 2 form.

  • sir i got 150 in afcat but not cleared ekt but in form i hv filled only one choice technical can i make changes now to call for ssb

  • sir i got 132 in afcat but not cleared ekt but in form i hv filled all branches so am I eligible for other branches & If yes which ssb center I should select since this is my 1st attempt in ssb

  • Sir I cant remember which branch I had applied for..I have cleared the cut off for afcat but not for can i know the branch I had opted for

  • sir i have cleared the AFCAT but due to software glitch ekt exam is not mentioned in my exam letter so when this exam is conduct and my call letter for ssb interview is also dispatched

  • Can a person with -5 and above power apply for technical and ground duties branch ? Will there be a problem in Medical?

  • Hi,

    Sir I am unable to login in my Afcat 2015 for downloading the admit shows an error Invalid login..I am worried plz suggest

  • Sir,
    In AFCAT 1 – 2015, I have cleared ekt by 9 marks but could not qualify AFCAT by 14 marks.
    Will I get a call for AFSB or not?

  • Hi,
    My domain is eee but i have selected computer for the EKT exam. Will this work if i pass the EKT.

  • sir/mam. I have done from electronics and communication.but on my admit cart the ekt subject is electrical and electronics.are these both branches same.

  • Sir..we apply all three branch’s but we pass in first paper and didn’t pass in ekt paper …in the case we call us for non tacnical or not???????please tell me sir

  • if i have applied for both technical and non technical posts but only qualify in afcat not in ekt , then i am eligible for ssb interview or not

  • Sir,i have cleared afcat exam but hav’nt applied for ekt at registration time.I am from computer sci engg.What should i do now,whether to go for SSB or reapply again next time.please guide me.

    • Its Okay if you haven’t applied for EKT, it only means that you will not be applicable for technical branches in SSB Interview but you will be eligible for other branches.

  • i have applied for technical entry..i have passed my AFCAT and did not clear my EKT.. but i got a call letter.. so will i attend technical or flying?? in case of flying should i undergo PABT??

    • You will not attend technical since you didnt clear EKT, if this is your first attempt of AFSB then you will get the opportunity for PABT based on your eligibiity.

  • Hi Sir,

    I got a letter for my EKT exam to be held on 21st Feb. If I pass this exam, what be the schedule after that? When will I get a call for AFSB (5 day schedule)?

  • Sir, I want to apply for ground duty branch but by mistake I applied for EKT subject, and i choose ground duty branch as first preference and then flying branch and next technical branch. So what would I do if I want ground duty branch and I’m not interested in technical branch. Will I want to attempt EKT subject or not? Please help me

  • sir for next year what will be the age limit of these all branches in the information for 2016 exam age limit from 2nd july 1991to 1997 so for next year it will become 2july 1992??

  • Hello Sir.I have filled AFCAT 2017.i have applied both for technical and non technical..I m from CSE engg.And i have made technical as first order of preference.Is it necessary for me to appear for EKT?Or If i fail Ekt n pass afcat.Can i be called for ssb for non technical?
