Formats of Different Certificates Etc Needed in an SSC exam



i) Typing is Essential (IMPORTANCE)

In this exam how high you score in the written is; is worthless unless you are able to qualify the type test. So to learn typing at the needed speed becomes a must for this exam. If a person knows typing; he must do practice for atleast 20 minutes daily; and if a person is fresher he must start it learning from this very moment (40-45 minutes at least for daily). Otherwise the things will be disastrous. .

It is seen that many of the candidates become serious to their typing after the written result, when much time in not left to learn it. Learning type and gaining the required speed generally requires 5 months. So start it well in advance.

One more thing: Do your practice on the PC using TVS keyboard as in the exam hall they are TVS boards usually. If you do it on the LAPTOP, attach it with a TVS keyboard while practising.


Well, if we see the DATA ENTRY SKILL TEST is no different than a typing test; in which we have to do typing on the computer @ 8,000 characters per hour i.e. almost the speed of almost 27 wpm (words per minute) . Whereas for the post of LDC it’s 35wpm. The difference is big; and therefore that might be one of the reasons of higher cut-offs for the post of DEO.

iii) No Certificate For Skill Test


iv) Learn Typing; Be an LDC/DEO

The final cut-offs of any exam are generally much higher than that we see them in the written part of the examination. But in CHSL exam cut-offs for the post of LDC and DEO do not show that big difference. Whatever that increase is in the cut-offs, it’s not as substantial. I mean to say it’s only because of typing being an essential part of the exam. Had typing not been compulsory the situation would certainly have been different.

As many of the aspirants in this exam are CGLE left-out cases; marks equal to the cut-off become so easy to score in a CHSL exam. From my experience I have seen that the candidates scoring very high in the written part are not generally found that good in typing. So I’m certain if YOU ARE OK WITH YOUR TYPING THE POST OF LDC/DEO IS YOURS.

v) Time Required to Learn Typing

It actually depends on an individual how much time he takes to gain typing speed at 35wpm. But generally it takes 5-6 months. Starting typing learning from an institute does help but if you are not comfortable in finding an institute nearby you can learn it at home too. In both the cases utmost sincerity is required.

vi) Is Backspace Allowed in Skill-test?

QUERY: In DEST, do we have to type in MS word or in any other software application? If any other application software, is back space allowed in that? The passage given will be hard copy or soft copy?

REPLY: This is their own software which has been programmed for time-set, recognition of errors and measuring speed etc. But this is like MS WORD; means they give a certain printed (HARD COPY) passage that we have to type like the we do in MS WORD. Backspace is allowed. In fact this is very simple passage and hardly containing any special character. Figures too are 4-5 generally. Errors are not shown/underlined. NOT A BIG DEAL OF COURSE!

vii) Is it Essential to Appear in Both Skill Tests?

QUERY: If I qualify for the both posts, shall I be given any option to choose or have to appear in both skill tests? And what if I fail too qualify one or both?

REPLY: If you qualify for both the posts you’ll be called for both the skill tests. If you fail to qualify one of them you’ll be selected for the other post; and if you fail in both the skill tests you wont be selected for any of the posts. If you qualify both the skill tests you’ll selected for the post which you preferred at the first place.

Both the tests are held in one single day; one in the morning and the other in the evening.


Are HCF and LCM, BOAT and Streams etc in Syllabus of CHSL (10+2) Exam?

QUERY: There is no mention of H.C.F and L.C.M, boat and stream etc. chapters in this new syllabus. Can we infer that no question will be set from these chapters?

REPLY: They are a must to do; they are all parts of other chapters given in the syllabus. For example, H.C.F. & L.C.M. are parts of NUMBER SYSTEM and Boat and stream is part of TIME AND DISTANCE.


Difference between LDC, STENOGRAPHER AND DEO? Which job is better?

LDC (LOWER DIVISION CLERK)—-LDCs are generally found in every office. He is supposed to do only the clerical work which is very very simple in nature like diary (receipt of documents), dispatch, making of salary bills of the staff, handling of various other documents etc. He is in the GRADE PAY of Rs 1,900.

DEO (DATA ENTRY OPERATOR)—-His work is generally feeding of various data in the computer in addition to doing some clerical work. They are in two GRADE PAYs 1,900 & 2,400.

STENOGRAPHER—-A stenographer is mainly attached with a senior officer; who has to first write that officer’s speech in steno & then type the same. I’m not aware of the GRADE PAY that they are associated with as the ADVERTISEMENT is silent on it.
