Student Resources

Places to go when the notes and videos are not enough.

💻 Technology

• TI-84 Calculator Guide — Texas Instruments' own guide for the TI-84 Plus CE, with tutorials and worked examples.
• Canvas Student Guide — How to submit assignments, check grades and use the Canvas app.
• Desmos Graphing Calculator — Free, fast and genuinely good for seeing what a function does.
• WolframAlpha — Useful for checking your work — not for producing it.

🏫 College of Lake County

• CLC Library — Research materials, databases and quiet places to work.
• Mathematics Department — Programs, course sequences and department contacts.
• Student Success Resources — Advising, accessibility services, counselling and financial aid.
• Tutoring Center — Free maths tutoring, online and in person. Current hours are on the CLC page — check there rather than relying on a date typed into Canvas.

📚 Learning and practice

• OpenStax Mathematics — Free, peer-reviewed textbooks, including a precalculus text.
• Khan Academy — Video lessons and practice from basic algebra through calculus.
• 3Blue1Brown — Visual explanations of why the mathematics works, not just how.
• Paul's Online Math Notes — Thorough notes and worked examples for algebra through calculus.

🎓 Where this leads

• AMS Career Resources — What people actually do with a mathematics background.
• MAA for Students — Competitions, undergraduate research and student programmes.

Start with the Tutoring Center. It is free, it is staffed by people who teach these courses, and students who go early do better than students who go once they are in trouble.
