Of these ways to enter the CBI, two of them LDC and Sub-Inspector are from the exams conducted by SSC. In this article, we will focus on the post of Sub – Inspector in this post. The post of LDC will be covered in detail in a separate article.
Salary – CBI sub-inspector is a group – B post with a-grade pay of 4600/- which means the starting basic pay of Rs. 44900/-. It is one of the highest paying jobs in all of SSC CGL jobs due to the special incentive allowance of 20% and 13 months pay. Watch my video on the salary of a CBI SI here – https://youtu.be/X9vRAiRg54o
Power, prestige, and social respect – It is also the only post that gives you unparalleled power, prestige, and respect. I have detailed some of the incidents of the power of CBI in this video – https://youtu.be/fHWnCz-a328 (Tip: watch from 7:29 onwards for some juicy info)
Promotions – In CBI, you normally get 4 promotions, 5 at max if you are really lucky or if you join it at the age of 21 years. CBI is probably the only department in which the first promotion is sure-shot within 5 years. I give more details about the promotions in CBI in this video – https://youtu.be/zj22480HovM

|A. General Intelligence and Reasoning||25||50|
|B. General Awareness||25||50|
|C. Quantitative Aptitude||25||50|
|D. English Comprehension||25||50|
As this is a computer-based exam, it is held on multiple dates. The process of normalization is also done to smoothen out any anomalies caused due to variation in the difficulty level of the exam on various days.
Generally, it takes about 2 months for the results to be declared although it appears from the past few years that it may take anywhere from 4 to 6 months, maybe even more. The cut-offs of this exam generally go pretty high. In 2019, the cut-offs were about 142 marks. There were about 2000 candidates above 182. Due to normalization, the scores of some of the candidates even go higher than the maximum marks i.e. 200.
The tier-II exam (Also called the SSC Mains exam) is generally held about 1.5 months from the date of declaration of results of Tier-I. The details of this exam are as under –
|Subject||Number of questions||Number of marks||Time allowed|
|I Quantitative Aptitude||100||200||2 hours|
|II English Language and Comprehension||200||200||2 hours|
Things to keep in mind –
- Tier-I and Tier-II will consist of Objective Type, Multiple choice questions only. The questions will be set both in English & Hindi except for English Comprehension in Tier-I and Paper-II in Tier-II.
- In Tier-I, there will be negative marking of 0.50 for each wrong answer.
- In Tier-II, there will be a negative marking of 0.25 for each wrong answer in Paper-II (English Language and Comprehension) and of 0.50 marks for each wrong answer in Paper-I, Paper-III, and Paper-IV.
- In Tier-II, Paper-I and Paper-II are compulsory for all the posts.
This exam is the most important for your success in SSC. You can afford to mess up a little in the tier-1 exam but you cannot afford to mess up in tier-2. I myself recovered my poor score of tier-1 in tier-2 both times, I cleared SSC. So make sure to master your Maths as well as English pretty well.
|Mode of Examination||Scheme of Examination||Maximum marks|
|Pen and Paper Mode||Descriptive Paper in English or Hindi (Writing of Essay/ Precis/ Letter/ Application etc.)||100|
Things to remember
The Paper in Tier-III will have to be written either in Hindi or in English. Part paper written in Hindi and Part in English will be awarded zero marks.

Things to remember
- In my opinion, the level of Tier – II remains almost identical to the level of Tier – I. Also, keep in mind that the syllabus is also the same for both the tiers.
- On some shifts, the level of exam is very high while on some of the shifts, it is pretty low. To make the level playing field equal for every candidate, the process of normalization is conducted.
- Note that there’s no data entry test/ Computer proficiency test for the post of sub-inspector in CBI.
Tier – III
Tier – 3 is essay writing exam. You can adopt either English or Hindi for this purpose. You cannot however mix these languages in one paper.
The combined results of all the tiers are declared about 2-3 months after the conclusion of the tier-III exam. Although for the past 2-3 years, SSC has taken much time to declare results at all levels.
After the results of the all the tiers have been declared, its time for the verification of documents of all the successful candidates. The candidates are required to bring with them the following documents in 3 photocopies –
- 10th Mark sheet/passing certificate
- 12th Mark sheet/passing certificate
- Birth certificate (optional)
- Graduation Mark sheet (print out of the results of those candidates who applied in their final year)
- Caste/Category Certificate -if applicable
- Physical handicap certificate – if applicable
- Relevant certificate is seeking age relaxation
- No objection certificate if already employed in government/ govt. undertakings
- Any other document mentioned in the SSC notification.
- 3 passport size recent colour photographs
- Government issued ID proof original (Aadhar, Driving License, PAN card, passport etc)
At the time of document verification, the candidates are given the post preference forms. They have to fill their choices in decreasing order of preference. Please note that a candidate will not be considered for a Post and Ministry /Department /Organization if he/she has not indicated his/ her preference for it. Options confirmed at the time of document verification will be treated as final and will not be changed subsequently under any circumstances. Therefore, candidates are advised to be careful in exercise of such options.
If you are aiming for SI in CBI, you must fill in this post at number 1 spot. Note that there is no location preference for this post as locations in CBI are decided by the CBI itself after the training of the candidates. In CBI, you are liable for all India transfer.
Also note that there is a set of physical standards prescribed for CBI and some other posts, so you must fill in these posts only if you qualify their Physical criteria.
After the document verification, the final results are declared about 2-3 months later. Again, looking at the trend for the past few years, the SSC has been too lazy to declare the results.
Note that there is an individual paper-wise cutoff for every paper of Tier – II i.e. Maths and English. It means that you cannot just score well in one subject and can afford to trail behind in another. You have to clear the individual cut off in both the subjects. It is generally not that high so you wouldn’t have to worry about it. But what you do have to worry about is the combined cutoff.
There is a cut-off criterion for a combined score of tier – I and tier – II exams. If you fail to clear that cutoff, you won’t be considered for the tier-III exam. So prepare for both the exams well.
