Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 1/5
Pure germanium is doped with a small amount of phosphorus. The resulting semiconductor is
- A. n-type, with electrons as majority carriers
- B. p-type, with holes as majority carriers
- C. intrinsic, because phosphorus forms four bonds
- D. an insulator, because doping widens the band gap
Example 3 · difficulty 1/5
Silicon doped with boron becomes p-type because each boron atom
- A. supplies a weakly bound fifth electron
- B. creates an incomplete covalent bond that can accept an electron
- C. removes the valence band completely
- D. contributes a freely moving proton
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 2022 Physics Semiconductor Electronics 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 2022 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.
