Diploma & polytechnic

Second hand diploma and polytechnic books online

Polytechnic semesters are short and the prescribed books are branch-specific, which means a diploma set has almost no value to the student who finishes it and a lot of value to the batch behind. Find mechanical, civil, electrical, electronics and computer semester books here.

A student's guide to buying Diploma books second hand

Short semesters, branch-specific books

A polytechnic diploma runs three years in six short semesters, each with five or six branch-specific prescribed books. The books are read for a few months, used in the exam, and then have no further role — the student either enters the workforce or moves into a lateral-entry degree with a different reading list.

That leaves a large, predictable supply of recent diploma books in mechanical, civil, electrical, electronics, computer and automobile branches, which is what this page collects.

  • Branch core subjects for each semester, from applied mechanics to workshop technology.
  • Engineering mathematics, physics and chemistry for the first-year common semesters.
  • Printed drawing textbooks and lab manuals.
  • Question banks and previous-year papers for your state board of technical education.

Matching a set from another state board

State boards of technical education publish their own curricula, so chapter ordering and paper codes differ. The underlying subject content — strength of materials, electrical machines, thermal engineering — is largely common.

The practical approach is to match the prescribed title and author from your own syllabus rather than searching by subject name alone. The listing records the course, branch and edition for exactly this check.

Buying a whole semester cheaply

Diploma books are cheaper than degree references to begin with, which makes delivery a larger share of the cost. Ordering the semester in one cart keeps that inside a single ₹100 slab per five books instead of paying a slab per order.

Where a title is unavailable, checking again after the next exam season usually works — listings from finishing batches arrive in waves.

Selling after your diploma

The batch behind you needs your exact set, and they need it in the fortnight before their semester starts. List with the branch and semester in the title and bundle the set.

Prices are suggested at about 25% of MRP, and proceeds withdraw to UPI in multiples of ₹100.

How buying used works here

Every listing checked, condition graded

Every listing is reviewed before it goes live and carries a Like new, Good or Fair condition tag with real photos.

Student-set prices

Sellers are guided to price at about 25% of MRP, so most books cost a fraction of a new copy.

Cheap bundled delivery

Delivery is charged in slabs of ₹100 per 5 books, so ordering a full set stays affordable.

Questions students ask

Will a set from another state board of technical education match my syllabus?

Core subject content is largely common, but chapter ordering differs. The listing records the course and edition, so match the title and author to your prescribed list.

Are drawing sheets and manuals included?

Printed drawing textbooks and lab manuals are listed. Used drawing sheets are not.
