CG PET vs BCECE: Two State Engineering Routes That Work Completely Differently
CG PET and BCECE both sit under "state engineering entrance exam," and that label hides how differently the two are actually built. CG PET (Chhattisgarh Pre Engineering Test) is Chhattisgarh's own state route into its engineering colleges. BCECE, at least the PCM route covered here, is not Bihar's primary engineering admission path at all: that is UGEAC, run on JEE Main 2026 scores. BCECE PCM exists for remaining engineering vacancies once the primary counselling round is done, a genuinely different role than CG PET's.
- CG PET has no negative marking at all: +1 for correct, 0 for wrong or unanswered, across 150 questions in 180 minutes.
- BCECE PCM deducts a full mark per wrong answer across 300 questions worth 1,200 marks, more than triple CG PET's paper length.
- CG PET uses one free-roam 180-minute timer with no subject locking. BCECE PCM locks you into Physics, then Chemistry, then Mathematics, 90 minutes each, with no way back once a subject's window closes.
- BCECE PCM is a vacant-seat route, not Bihar's primary engineering admission path; that is UGEAC, run on JEE Main 2026 scores.
CG PET vs BCECE PCM at a glance
| CG PET | BCECE PCM | |
|---|---|---|
| Questions | 150 | 300 |
| Total marks | 150 | 1,200 |
| Duration | 180 minutes, one timer | 270 minutes, three locked 90-minute windows |
| Scoring | +1 correct, 0 wrong | +4 correct, -1 wrong |
| Subject navigation | Free, across all three subjects | Locked: Physics then Chemistry then Mathematics, no return |
| Role | Chhattisgarh's own state entrance | Bihar's vacant-seat route after UGEAC/JEE Main counselling |
CG PET: no penalty, no lock, straightforward pacing
CG PET's 150 questions split evenly across Physics, Chemistry, and Mathematics, 50 each, and the entire paper sits under one 180-minute timer with free movement between all three subjects. With zero negative marking, an educated guess never costs you anything beyond the time spent, which changes how you should approach a question you are not fully sure of compared to almost every other exam on this site.
BCECE PCM: three papers wearing one exam's name
BCECE PCM's 300 questions (100 each in Physics, Chemistry, Mathematics) are worth 4 marks correct and lose 1 mark wrong, the same scoring shape as JEE Main. What actually separates it from a normal single-timer mock is the three-part lock: Physics gets its own 90 minutes and auto-submits when time runs out, then Chemistry gets a fresh 90 minutes with no way back into Physics, then Mathematics closes the paper the same way. You cannot bank spare time from a subject you finish early and spend it on the next one.
BCECE PCM's three 90-minute windows do not let you borrow time between subjects. Finishing Physics in 70 minutes gives you nothing extra in Chemistry.
Why the vacant-seat distinction matters
If you are a Bihar-based PCM student, BCECE PCM is not where your primary engineering-admission attempt should go. UGEAC, which uses your JEE Main 2026 rank, is the regular first-year counselling route into Bihar's government engineering colleges. BCECE PCM sits alongside it for seats that remain unfilled once that primary process finishes, worth preparing for as a genuine backup rather than a first-choice plan.
Practice tests for both are on this site: CG PET and BCECE, both under the engineering exams directory. If locked subject timers are new to you, sectional lock vs composite timer covers the general strategy shift a locked format demands.
Frequently asked questions
Is BCECE the main way to get into a Bihar government engineering college?
No. The primary route is UGEAC, which uses JEE Main 2026 scores for the regular first-year counselling. BCECE PCM is a separate route for engineering seats that remain vacant after that primary counselling round, worth preparing for as a backup, not a first-choice plan.
Does CG PET have negative marking?
No. CG PET awards 1 mark for a correct answer and deducts nothing for a wrong or unanswered one, across 150 questions in 180 minutes.
Can I move between Physics, Chemistry, and Mathematics freely in BCECE PCM?
No, and this is the biggest structural difference from CG PET. BCECE PCM locks you into Physics for 90 minutes, then Chemistry for a separate 90 minutes with no return to Physics, then Mathematics for a final 90 minutes, with no time borrowed between any of the three windows.
Which exam has more questions, CG PET or BCECE?
BCECE PCM, by a wide margin: 300 questions worth 1,200 marks, against CG PET's 150 questions worth 150 marks. BCECE PCM's paper is exactly twice as long and worth eight times the marks.
