AP chem class

Looking for study advice for an AP Chemistry class that doesn't follow the AP Classroom unit order. The teacher groups topics differently and includes a lot of labs. The exams focus heavily on multi-step problem solving and calculations rather than typical AP-style questions. The goal right now is to get good grades in the class, not to prepare for the AP exam yet.

Exam 1 covered kinetics. It reviewed stoichiometry, gravimetric analysis, chemical reactions and balancing equations, then moved into rate laws, reaction orders, mechanisms, graphs and half-lives, and the integrated rate law. The labs were Percent Copper in Brass using Beer's Law, Decomposition of Hydrogen Peroxide (rate law), the Eight Solutions Lab, and Crystal Violet (integrated rate law).

Exam 2 covers gases, solutions, liquids and solids. The topics are net ionic equations, solutions, phase changes, solubility curves, phase diagrams, and the properties of liquids, solids and gases. That includes metathesis net ionic equations that produce gases. The labs are Molar Volume of a Gas (two versions), Determination of the Density of CO₂, a design lab on the Rate of Decomposition of CaCO₃, Column Chromatography, and The Formula of a Hydrate.

What's the best way to study? Recommendations for practice problems with worked solutions would be great, whether from textbook chapters, websites or YouTube channels. Tips for lab-based calculation questions would also be appreciated. Thanks!

68% on first unit test but thought I did great

Basically what the title says. I studied, did a practice quiz (got 85 and brushed up on the things I missed) and then took my actual unit test and got 68. The test didn't feel too hard, I have no idea what went so wrong. It was unit 1 and my friends all got 89 and up. I'm so frustrated and was wondering if anybody had study tips? I can not spend hours watching videos but if y'all have had success playing something in the background or practice tests that help that'd be great

Also: My teacher only lets us look at our tests once and so I haven't been able to see my test or mistakes yet and will only be able to do so when I do test corrections.

Thanks!

frq help 3.4

can anyone explain how to do these two problems? im assuming the answer the a is 1 mol CO2 and the answer to b is 5.00atm-1.63atm but im not 100% sure.
