Sample Questions (Chemistry) for LUMS SSE Admission Test
The admission test (Chemistry), for LUMS SSE, would consist of several multiple choice
questions (MCQ) with 5 options. There will be one mark for each correct answer and 0.25 marks
will be deducted for every wrong answer. The time duration for this test would be about 90
sec/question. Calculators will not be allowed during the exam but a simple periodic table will be
provided. The questions below are just an indication of general format of the exam that would
consist of almost equal concepts from physical/inorganic/organic chemistry sections, and not
only the concepts covered in these sample questions.
