STS Releases MDCAT Answer Key 2026

SIBA Testing Services (STS) Officially Releases MDCAT 2026 Answer Keys for All Paper Versions

SIBA Testing Services (STS) has officially released the MDCAT 2026 answer key for medical and dental college aspirants who appeared in the high-stakes entrance examination held on Sunday, September 20, 2026.

Covering nine designated regional testing facilities across Sindh and the federal capital, the release allows thousands of candidates to cross-verify their attempted responses, calculate preliminary aggregate metrics, and gauge their competitive standing long before the formal merit lists are compiled.

Breakdown of Test Centers and Administration Scope

Administered under stringent surveillance, biometric verification, and standardized testing guidelines, the STS MDCAT 2026 examination spanned nine major regional hubs.

• Sindh Centers: Karachi, Hyderabad, Jamshoro, Mirpurkhas, Shaheed Benazirabad (Nawabshah), Larkana, and Sukkur.

• Federal Capital Center: Islamabad (accommodation for designated regional domicile quotas).

Key institutional venues included major engineering and medical campuses such as NED University and Dow University (Ojha Campus) in Karachi, Public School Latifabad in Hyderabad, LUMHS in Jamshoro, and dedicated regional public school grounds. The 180-minute marathon evaluation proceeded without major logistical disruption, adhering strictly to Pakistan Medical and Dental Council (PM&DC)-aligned curriculum standards.

Comprehensive Paper Codes: Versions A, B, C, and D

To safeguard test integrity against prompt sharing and sequential peeking, STS deployed randomized question shuffling across four distinct booklets: Version A, Version B, Version C, and Version D.

Candidates must retrieve the exact answer key corresponding to the serial code imprinted on the carbon-copy duplicate of their OMR response sheets handed out upon exiting the examination halls.

Frequently Asked Questions (FAQs) on STS MDCAT 2026 Assessment

• Can I challenge discrepancies in the STS MDCAT answer key? Yes, candidates identifying verified typographical or scientific key errors can submit formal review representations through the designated STS portal window within the stipulated deadline (typically 7 to 10 days post-release).

• Is the carbon copy mandatory for score calculation? While recommended for exact line-by-line matching, reconstruction via memory without a carbon copy leaves room for human error; official evaluation strictly references OMR sheets scanned directly by STS optical readers.

• When will final medical college admissions commence? Following objection resolution and score normalization, provincial admission committees will release synchronized merit lists for public and private sector MBBS/BDS seats.
