CHSE Odisha Elective Electronics exam-day guide
CHSE Odisha Elective Electronics · Prepare for the day ahead.
Your checklist
Admit card
Carry the original CHSE admit card for the practical exam, signed by your principal. Keep it in a clear plastic folder and put a photocopy in your bag as backup. Entry may be refused without it; confirm the exact requirement with your school.
School ID card
Bring your current school identity card with photo and roll number for verification at the centre.
Practical record book (journal)
Bring the completed record book with an index, all experiments written up, circuit diagrams, observation tables, calculations, and your teacher's signature. Use the same book you maintained during the year; do not rewrite it overnight.
Stationery
Two blue or black ball pens, one pencil, eraser, sharpener, and a 15 cm scale. Avoid gel pens that smudge on graph paper.
Non-programmable calculator (needs_review)
Bring a simple non-programmable calculator only if your school confirms it is allowed in the electronics practical. Confirm with your teacher; rules vary by centre.
Multimeter (needs_review)
Bring your own multimeter only if your school has instructed you to. Most centres provide instruments, so do not assume. Confirm with your teacher.
Component kit and breadboard (needs_review)
Your school may ask you to bring a small kit: resistors, capacitors, diodes, transistors, IC 7400/7408, breadboard, and connecting wires. Confirm the exact list with your teacher; many centres supply components.
Soldering kit (needs_review)
If a soldering experiment is part of your syllabus, confirm whether you must bring an iron, solder, flux, and stand. Many schools provide them. Do not bring a soldering iron unless told to.
Graph paper and rough sheets
Carry two or three sheets of graph paper and plain rough paper for calculations and rough circuit sketches. Confirm whether the centre supplies them.
Lab coat or apron (needs_review)
Wear a clean lab coat or apron if your school requires it for practical exams. Confirm the dress code with your teacher.
Simple wristwatch
Wear a non-smart wristwatch to pace yourself. Smartwatches and mobile phones are not allowed in the examination hall.
Water bottle and light snack (needs_review)
Carry a transparent water bottle and a light snack only if the centre permits. Keep them outside the lab bench. Confirm the centre's policy.
Plan the day
Finish your record book: complete the index, write up every experiment, draw diagrams in pencil, tabulate observations, and get your teacher's signature. Revise the core experiments likely to be asked, such as half-wave and full-wave rectifiers, zener voltage regulator, transistor CE amplifier, logic gates, and basic soldering. Practise drawing neat circuit diagrams from memory. Confirm reporting time, venue, and whether you must bring components or instruments.
Pack your bag: admit card, school ID, record book, stationery, calculator if allowed, and any confirmed components. Rehearse viva answers: function of each component, working principle, and precautions. Do not start a new experiment. Sleep at a normal time; practical exams reward steady hands and clear thinking.
Eat a normal breakfast and avoid heavy or oily food. Arrive at least 30 to 45 minutes early. Check the notice board for your batch and seat. Keep your bag light and leave your phone and smartwatch at home or with a guardian. Wear the prescribed uniform or lab coat.
Read the whole question paper first and choose the experiment you can perform most reliably. Verify components with the multimeter before wiring. Keep the power supply off while making connections. Draw the circuit diagram before assembling the circuit. Record raw observations directly on the answer sheet, not on loose scraps. If an instrument is faulty, raise your hand and ask the invigilator; do not swap equipment yourself. Reserve the last 10 minutes to check units, significant figures, diagram labels, and prepare for viva.
Rules to check
Carry your original admit card and school ID at all times. Entry to the lab may be refused without them; confirm with your school what to do if a document is lost.
Mobile phones, smartwatches, and programmable devices are not allowed in the examination hall. Leave them at home or outside the lab.
Follow lab safety: switch off the power supply before changing connections, never touch a live circuit, and hold a soldering iron only by its insulated handle. Report any burn or shock to the invigilator immediately.
Do not borrow or exchange components, instruments, or record books during the exam. If you need something, ask the invigilator.
Your record book must be your own work and carry your teacher's signature. The viva examiner may ask you to explain any experiment written in it.
Breaks are usually not permitted during the practical. Ask the invigilator if you need to use the restroom; confirm the centre's policy in advance.
Scoring typically combines the record book, experiment performance, and viva. Confirm the exact mark split and pass criteria with your school; do not rely on hearsay.
If you finish early, recheck circuit connections, observation tables, units, and diagram labels. Do not leave the lab until the invigilator permits you to.
