Pass ELEC3120
with an AI that actually reads your lectures.

LearningPacer is a virtual TA built on the real ELEC3120 lecture decks. Every answer cites the slide it came from — no hallucinations, no generic textbook fluff.

Grounded in ELEC3120 L01–L17 with page-level citations6 models · live switchMock paper → PDF

FOUR MODES, ONE TUTOR

Built for how engineering students actually study

Tutor Mode

Ask any concept — TCP cwnd, ARP poisoning, CSMA/CD — and get an Answer / Warrant / Evidence breakdown with Mermaid diagrams and LaTeX equations.

Code Mode

Socket programming, Wireshark filters, traceroute scripts. Inline syntax-highlighted code with explanations, not just copy-paste.

Image Mode

Upload a past-paper figure or hand-drawn topology. The AI reads it, explains every node, and walks through the answer.

Agent Mode

One click → a full mock final exam PDF, complete with cover page, MCQs, structured questions, and an answer key.

WHAT MAKES IT DIFFERENT

Three things no general-purpose chatbot does

01

Cited from real lectures

Every claim links back to a specific lecture and page. If GLM-4.6 says "see L07 p.14", you can verify it in one click. No more guessing if the AI made it up.

02

Multi-model, on demand

Switch between GLM-4.6, Gemini 2.5 Pro, Claude Sonnet 4, GPT-5, DeepSeek and Grok mid-conversation. Use the cheap fast one for definitions, the frontier one for hard derivations.

03

Built for HK students

Replies default to English; auto-switches to 繁體中文 when you write Chinese. Technical terms (cwnd, RTT, MAC) always stay in English. Cantonese-friendly tone.

WHY NOT JUST USE CHATGPT?

"It's the only AI that knows what 'L07 slide 14' actually says — and tells me when I'm wrong, with the page reference."
