DIAGNOSTIC TEST IN CHEMISTRY
(Secondary Level)
Dear Friend
I wish to collect some information regarding the difficult areas (in learning
Chemistry) at Secondary School level. In order to identify the specific
areas of difficulty in Chemistry, I have developed a two-tier diagnostic test
in Chemistry. This test consists of 50 multiple-choice questions. Each
has two sections.
A. Answer for the question and
B. Reason for the answer
For each question find the correct answer and identify why your answer is
the correct one. Please mark your responses in the separate sheet given.
with a
./
mark. Kindly go through the test and give answers to all the
items.
Thanking you.
