Purpose The purpose of this case study is to share the authors’ involvement and observation in adopting online exam as an evaluation tool, in the hope that others may too be able to adapt and circumvent this lockdown period while bringing a more reliable methodological approach in an online exam. Design/methodology/approach This is a case study that reports the application of an online examination for a year 3 MBBS Professional Exam during the period of lockdown (movement control). This case highlights the conduct of online theory in the form of single best answer multiple choice questions and online practical via objective structured clinical examination, without jeopardizing the integrity of the system, and the measures adapted to mitigate potential academic dishonesty. Findings The authors’ observation shows that online exam can be conducted in scenario where conventional exam is not possible. Research limitations/implications This is an observation in a real-life scenario that discusses the purpose and the process. A single study may not be sufficient to relate the reliability and generalizability of the analysis. Practical implications The practice of social distancing is a hindrance towards traditional classroom teaching. Online exam has promising potential to be the solution to this problem. The authors have demonstrated that an MBBS theory and practical exam can be conducted remotely without any physical contact, without any compromise in achieving the learning objectives within the curriculum. Medical education can proceed with a new drive while ensuring the learning process continues a stable momentum. Originality/value Online examination is almost unheard of, especially for undergraduates in the medical programme. This study highlights a plausible approach in the design of the online examination and identifies the barriers and favourable edges of this platform.
