Your preparation plan from TODAY
I would divide your preparation into 4 stages.
Stage 1 — 24–25 August
Eligibility + application + syllabus setup
Stage 2 — 26 August–1 September
Core technical preparation
Stage 3 — 2–5 September
CPCB/environmental + technical revision + mock tests
Stage 4 — 6–7 September
Final revision + application verification
STEP 1 — Do this TODAY
Before studying, determine exactly which post you should target.
The current notification information gives these broad requirements:
Scientist-B
First-class Master’s in Environmental Science/Natural Science or eligible engineering/technology degree, with the prescribed GATE >90 percentile or NET-JRF requirement and relevant experience. There are 12 posts.
Scientific Assistant
First-class Master’s in Environmental Science/Natural Science or eligible engineering/technology degree, with the prescribed GATE >90 percentile or NET-JRF requirement. There are 13 posts.
Field Assistant
12th Science with minimum 55%, plus knowledge of water/wastewater sampling and sample preservation. There are 8 posts.
Data Entry Operator
First-class B.Sc/BCA, plus MS Office skill test and typing requirements: 45 WPM English and 35 WPM Hindi.
The senior Scientist posts require substantial experience/publication/technical-report requirements, so they aren’t simply open competitive-exam posts.
Do not assume you are eligible just because your degree sounds related. The exact notification should be your final authority.
STEP 2 — Your CPCB core syllabus
If you are targeting Scientist-B / Scientific Assistant, I would make the following your core syllabus.
A. Environmental Chemistry
Master:

You should be able to answer both:
“What is BOD?”
and
“Why does high BOD indicate organic pollution?”
B. Water Pollution
This should be very high priority.
Study:
Sources
- Domestic sewage

- SPCB role
- Consent mechanism
- Pollution control
- Penalties
- Powers
2. Air (Prevention and Control of Pollution) Act, 1981

I. CPCB itself
You absolutely need to know the organization you’re applying to.
Learn:
CPCB = Central Pollution Control Board
It is a statutory organisation under the Ministry of Environment, Forest and Climate Change. It was constituted under the Water Act, 1974 and was subsequently entrusted with functions under the Air Act, 1981.
You should be able to answer:

- CPCB vs SPCB?
STEP 3 — Technical preparation method
Don’t simply read textbooks for 10 hours.
Use this cycle:
Learn → Recall → Questions → Revise
For every topic:
1 hour: Learn concept
30 min: Make short notes
30 min: Questions
15 min: Recall without looking
For example:
BOD
Learn:
- Definition
- Principle
- Test conditions
- 5-day BOD
- DO measurement
- Calculation
- Factors affecting BOD
- Difference between BOD and COD
Then close your book and write everything you remember.
That’s much more effective than rereading.
Your daily schedule
If you can give 6 hours/day, follow this:
| Time | Work |
|---|---|
| 2 hr | Technical subject |
| 1 hr | Environmental laws/CPCB |
| 1 hr | MCQs |
| 1 hr | Revision |
| 1 hr | Interview/current environmental topics |
If you only have 3 hours/day:
| Time | Work |
|---|---|
| 90 min | Technical |
| 45 min | CPCB/environment |
| 45 min | MCQs + revision |

One thing I want you to do differently
Don’t try to prepare for all 9 posts.
Pick your strongest eligible post and make that your #1 target.
For example:
M.Sc Environmental Science → Scientist-B / Scientific Assistant may be the relevant targets if all notification conditions are satisfied.
B.E/B.Tech Environmental/Chemical/Civil → Scientist-B may be relevant if the specific qualification, GATE/NET-JRF and experience conditions are satisfied.
12th Science → Field Assistant.
B.Sc/BCA → Data Entry Operator, subject to the exact conditions
