No notes :( An online practice test is available for purchase: https://acsexamsinstitute.com/general-chemistry-first-term-practice-exam-online-tutorial/ Study guides can be purchased or use the free copies in the CIC :) The approximate question breakdown is: 0 Foundations 7% 1 Atomic Structure 10% 2 Electronic Structure 16% 3 Formula Calculations 7% 4 Stoichiometry 10% 5 Solutions and Aq Rxns 16% 6 Heat and Enthalpy 7% 7 Structure and Bonding 14% 8 States of Matter 13% There are 70 questions and you will have 110 minutes. (1 min 34 sec per ques). Practice timing yourself on questions. It is to your advantage to answer every question. You can usually eliminate one answer choice through reasoning. DO NOT WRITE IN THE EXAM BOOKLET, you can only write on the scratch paper, and must bubble in your answer on the bubble sheet. Bubble in your answer completely and clearly. If you need to change your answer, make sure you erase clearly. Scratch paper cannot leave the exam room and must be turned in. ` Ink Drawings Ink Drawings Ink Drawings Ink Drawings Ink Drawings Ink Drawings Ink Drawings Ink Drawings Ink Drawings Ink Drawings Ink Drawings Ink Drawings Ink Drawings Ink Drawings Ink Drawings Ink Drawings Ink Drawings Ink Drawings
