General Chemistry I diagnostic test
An independent 1:1 tutoring-support scope for General Chemistry I, based on the listed introductory concepts and sequence. It is not an official course offering or accredited university material.
Independent 1:1 tutoring with Mohammad Abusaif on Preply. Course names and outlines do not imply university affiliation or an official university exam.
30 questions. A clearer starting point.
All questions and answer explanations are in English. Four options, one best answer per question. No login, name or email required. No mandatory timer; allow about 45 minutes.
You can skip, go back and change answers. Your progress is saved on this device. After submission, see your score out of 30, a topic breakdown and explanations, then optionally discuss your results in a lesson on Preply.

Topic coverage is mapped to the supplied outline from The University of Jordan (0339101). Your university may organise topics differently. Share your own syllabus before your lesson.
- Organic chemistry topics are excluded.
- Analytical instrumentation such as HPLC, GC, and UV-Vis spectroscopy is excluded because it is not listed in this outline.
- Equilibrium, kinetics, electrochemistry, and nuclear reactions are excluded because they are not listed in this outline.
- Questions are original diagnostic items, not copied or adapted from the source syllabus, its named textbooks, or examinations.
