After so many excluded for evaluation and changed answers .. what you guys think will be the cut off?
Where did they mentioned that these are revised answer keys?
Getting 109 after checking with revised keys
I have a doubt , In the questions where 2 answers are given marks will be given if one of them is answered or both have to be answered ??
Any one answer is fine.
Getting 94 marksπŸ˜‘
They revised answer for NF question is 2NF? Answer should be 1NF.
when will be the cutoff declared?
111 marks according to final key !! Any odds for getting interview call?
what was your score earlier?
They have changed some correct answers to wrong answers 😑😑
103 as per the revised keys.
The answer for the minimum height of AVL tree question is floor(log(n+1)) but they have changed it to ceil(log(n+1))

The answer for the cylinder-tracks... question is 1250 but they have changed it to 1280

Remote procedure calls question has 2 answers but they have excluded that question

Many wrong answers in the final revised key
What is meaning of "Excluded for evaluation" means?

Is those marks given to all?
No maks won't be given for them as those questions are not considered for evaluation so basically we had 8 such question so 8*3=24 marks won't be taken for evaluation so the exam boils down to 216 marks.
No bro those questions won't get counted... like as there are 8 questions excluded for evaluation so the total full marks is 216
thanks :)
Consider someone who wasted 16 mins (8*2) mins in those 8 question,This is not done ISRO.In an exam of 90 mins , actually we got 80 mins (8-10 mins for marking answers),16 mins is pretty big number.
Will there be any further changes to the answer keys or this is the final one?? And what are the odds for getting called for interview am getting 115 according to the revised key?
@akash Exactly i solved 7 of the question 2-3 times and wasted about 15 min. And exam is of just 90 min not 150 min. For ICRB team error we will suffer.
Corrected,I think the anger got better of me.
@chaitanya knvs yes that's true. They changed correct answers to wrong 😑😠😑 but that 1280 is correct, though I wrote 1250 as answer.
I think in that question then have taken 1 kilobyte as 1000 bytes and got the answer as 1280 it is true in decimal(SI) units as kilo means 1000, but in binary 1 kilobyte is 1024 bytes then answer will be 1250 as we are dealing with memory related things that also be considered in binary perspective and answer can be 1250.They can give both 1280 and 1250 as answers as kilobyte has both the meanings

Hi Everyone,

As anyone who has appeared for ISRO exam would know that this year there were 8 questions with none of the options correct and 4 with multiple correct. Due to ICRB team fault in setting questions many of the students ended up wasting time 10-15 min in those question question which is huge considering that there was only 90 min for solving 80 question. As these questions were cancelled students who didn't attend them would have got an edge over others. So i request all applicant to mail ISRO regarding this issue and ask them to call people in higher ratio for interview. Many have already mailed, please do the same.  Send mail from your id registered with ISRO during exam, other id mail they aren't opening..

Mail id:

[email protected] (mail id of ICRB)

[email protected] (Mail id of Nodal Public Grievance Officer, Department of Space, ISRO)

Send two mails Keep Subject as

1. "grievance about Advertisement Number ISRO:ICRB:03:2019"

2. "Query- Scientist/Engineer-SC Recruitment –ICRB"


What to write?

  • Mention above reasons (IN OWN WORDS, IF EVERYONE SENDS SAME MAIL IT WILL BE TREATED AS SPAM). Add your own valid and logical justifications.
  • request them to call people in higher number of people per vacancy notified. They call in 1:8 ratio, mention call1:11 or higher. (BARC perhaps call in 1:20)
