Drexel University course study guides: CHEM 101, CHEM 102

Courses students often find difficult at Drexel University

A "weeder course" is an introductory class that students often find difficult and that may have high withdrawal or failure rates. At Drexel University, the courses below have predictable trouble spots, which is why students repeatedly search for "Drexel University course help."

CHEM 101 (General Chemistry I, 11 chapters, ~3 hr 15 min on Lorea) is commonly difficult because of specific skills: Stoichiometry and limiting reagent (Ch 4) is the single biggest failure point; then VSEPR molecular geometry (Ch 7); unit conversion and significant figures trip students in week 1; gas law problem setup (Ch 9).

CHEM 102 (General Chemistry II, 10 chapters, ~3 hr on Lorea) is commonly difficult because of specific skills: ICE tables and equilibrium setup; weak acid/base pH calculations; buffer and titration curve interpretation; entropy sign reasoning; balancing redox half-reactions.

How the Drexel University term is structured

Drexel University runs on 10-week quarters, not a 16-week semester. CHEM 101 and CHEM 102 still cover 21 OpenStax chapters - the same spine, compressed. That is why these sections feel like weeders: a stoichiometry week and a VSEPR week land back-to-back. Use the study guides to pre-load the next chapter before lecture, not after the midterm.

At Drexel University, CHEM 101, CHEM 102 are what the registrar prints. The study guides below follow those codes, not a generic subject page.

Prerequisite chains that matter

CHEM 101 is the prerequisite chain into CHEM 102. Do not start the second course until tonicity, cells, or first-term stoichiometry (whichever this pair uses) can come out of your hand without the slides.

What these Drexel University study guides include

Each Drexel University study guide is a full catalog page, not a teaser. You get the published code, the OpenStax chapter list (21 chapters across this hub), the weeder moves students miss on timed exams, and a free Lorea course with no signup. Jump from this hub into CHEM 101 and CHEM 102 or back to the college course study guides index if you need a different campus.

What does "weeder course" mean at Drexel University?

A weeder course is an introductory class known for high difficulty, withdrawal, or failure rates. On this hub, those commonly difficult courses are CHEM 101 and CHEM 102. CHEM 101 is especially difficult because of Stoichiometry and limiting reagent (Ch 4) is the single biggest failure point. CHEM 102 is especially difficult because of ICE tables and equilibrium setup.

Is Drexel University on semesters or quarters?

Drexel University runs a 10-week quarter for these intro codes. That calendar is 10 weeks of teaching time. The Lorea study guides are timed to chapter count and subject, not to sitting the whole 10-week quarter in one sitting.

How long do the Drexel University Lorea study guides take?

CHEM 101 is 11 chapters and About 3 hours 15 min on Lorea. CHEM 102 is 10 chapters and About 3 hours on Lorea.

What textbook do these Drexel University study guides follow?

CHEM 101 and CHEM 102 on this hub follow Chemistry 2e (OpenStax). Your section may assign a commercial book; the chapter titles on each study guide are the OpenStax sequence.

Can I get Drexel University course help without signing up?

Yes. Every live Drexel University study guide opens a free Lorea course. No account required.
