IU CHEM-C 117: Principles of Chemistry and Biochemistry I
C117 is IU's distinctive first chemistry course for science and pre-health majors: general chemistry principles integrated with biochemistry from the start, rather than the traditional gen-chem-only opener. It anchors the chemistry sequence and carries a serious workload reputation.

What makes it hard
The integration is the difficulty multiplier: you're learning general chemistry's quantitative core while simultaneously applying it to biomolecules, so there's no easy memorization lane. Exams are time-pressured and problem-based in a pre-med-heavy room, and students who follow lecture without daily problem work get their correction on exam one.
What you'll cover
- • Atomic structure and bonding
- • Stoichiometry and reactions
- • Thermodynamics basics
- • Intermolecular forces
- • Biomolecule structure and function
- • Equilibrium concepts
The CHEM-C 117 study guide
How to study for IU CHEM-C 117, step by step.
- 1
Make the quantitative core automatic early
Stoichiometry and equilibrium reasoning are embedded in everything C117 does, including the biochemistry. Drill the calculations daily until they cost no thought.
- 2
Work problems cold every day
Following lecture while practicing little is the classic setup for an exam-one shock in a pre-med-heavy room. Solve daily with solutions closed and redo every miss.
- 3
Learn structures as logic, not flashcard images
The biomolecule material rewards understanding why a structure behaves as it does (polarity, bonding, interactions) over raw memorization. The exam questions connect structure to chemistry deliberately.
- 4
Connect the two halves constantly
C117's whole design is general chemistry applied to biological molecules. When a concept appears in both contexts, study it as one idea. The integrated questions are where exams separate students.
- 5
Run timed practice before each exam
Time-pressured problem exams reward trained speed. Mixed sets under exam timing in the final week beat another pass through the notes.

FAQ
Is C117 at IU hard?
It has a deserved reputation: general chemistry's quantitative core and biochemistry's structural material at once, with timed problem-based exams in a pre-med-heavy room. Daily problem practice handles it; lecture-following alone visibly doesn't.
How is C117 different from regular general chemistry?
IU integrates biochemistry from the start instead of saving it for later courses. You apply gen-chem principles to biomolecules immediately. It suits the pre-health pipeline but means there's no pure-memorization lane through the course.
How do I pass C117?
Make the calculations automatic early, work problems cold daily, and study structures as chemistry rather than images to memorize. Then run timed mixed practice before each exam. Speed is part of what's tested.

BUS-K 201: The Computer in Business
K201 is the famous Kelley course nearly every IU business student takes: hands-on Excel and Access skills plus information-systems concepts, recently refreshed to add data analysis and AI emphasis. It's an I-Core prerequisite, and a whole Bloomington tutoring economy exists because of it.
BUS-A 100: Basic Accounting Skills
A100 is Kelley's one-credit introduction to the accounting environment of the firm, a fast tour of financial, managerial, audit, and tax perspectives, required of all business majors as the gate into A201 and A202.
BUS-A 201: Introduction to Financial Accounting
A201 is Kelley's financial accounting course: the mechanics, measurement theory, and economic context of the financial statements. It's an I-Core prerequisite required of all business majors and a course whose grade Kelley admissions and recruiters actually look at.
BUS-A 202: Introduction to Managerial Accounting
A202 is Kelley's managerial accounting course: product costing, cost-volume-profit analysis, budgeting, and performance evaluation. It's the internal-decision-making counterpart to A201 and the other accounting prerequisite for I-Core.
