NEET 2018 Physics Questions
Use this page to connect the official 2018 paper with current Physics practice. NeetVellum does not claim a chapter appeared in that paper until the official question and final key have been mapped.
Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 3/5
In a metre bridge experiment, a known resistance of 6 Ω is connected in the left gap and an unknown resistance X in the right gap. The null point is obtained at 40 cm from the left end of the wire. The value of X is:
- A. 4 Ω
- B. 6 Ω
- C. 9 Ω
- D. 15 Ω
Example 3 · difficulty 3/5
A potentiometer wire of length 10 m and resistance 30 Ω is connected in series with a battery of emf 5 V and internal resistance 20 Ω. The potential gradient along the potentiometer wire is:
- A. 0.5 V m⁻¹
- B. 0.2 V m⁻¹
- C. 0.75 V m⁻¹
- D. 0.3 V m⁻¹
The evidence-first practice loop
- 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
- 2. Attempt closed-bookExpose the concept or execution gap before rereading.
- 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions
Are these official NEET 2018 Physics PYQs?
No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.
How should I use the NEET 2018 paper?
Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
