Learn C++ from zero — the language behind game engines, high-frequency trading and operating systems.
Bite-sized C++ lessons, data structures & algorithms (DSA) practice, and an AI mentor that turns cryptic compiler errors into plain English.
Built for complete beginners, CS students and coding-interview candidates.

WHY LEARN C++?
• C++ is the performance language: game engines (Unreal), embedded systems, robotics, finance and OS kernels run on it
• DSA in C++ is the classic coding-interview stack — practice here is practice for the job you want
• Learning C++ makes every other language feel easy: you'll understand memory, not just syntax
• Decades old, still everywhere — C++ skills don't expire

WHAT YOU'LL LEARN
• C++ fundamentals — variables, types, operators and control flow
• Functions, scope and program structure
• Pointers, references and memory — explained so they finally make sense
• Object-oriented programming — classes, inheritance and polymorphism
• The STL — vectors, maps, sets, iterators and algorithms
• Data structures & algorithms practice for coding interviews

EVERYTHING YOU NEED TO LEARN C++
• AI Mentor — stuck on pointers or a wall of template errors? Ask anything and get a clear answer in seconds
• 100+ bite-sized lessons (5–10 minutes each) — hard topics, small steps
• Real code editor — write, compile and run C++ code right on your phone
• Quizzes and coding challenges after every topic to lock in what you learn
• Weekly Code Challenge — compete with learners around the world
• Certificate of completion — pass the final exam and prove your skills
• Streaks, progress tracking and smart reminders to keep you consistent
• Learn on the go — lessons load fast and keep working on flaky connections
• App available in 22 languages

WHO IT'S FOR
• Beginners who want a serious language with serious payoff
• CS students who need C++ for coursework — and DSA for interviews
• Game development hopefuls heading toward Unreal Engine
• Developers from higher-level languages who want to understand what's under the hood

INTERVIEW MODE
The DSA lessons are structured like real interview prep: learn the data structure, see the pattern, then solve problems in rising difficulty — with the AI Mentor as your always-available whiteboard partner.

Learn cybersecurity from zero and prepare for the CompTIA Security+ (SY0-701) exam in one app — no IT background required.
Short lessons, performance-based questions (PBQs), timed mock exams, hands-on labs and an AI mentor, all mapped to the five Security+ objectives.
A cyber security learning app built for beginners, students and IT professionals changing careers.

WHY THIS CYBER SECURITY COURSE?
• One path from the basics to exam day: lessons first, then practice, then a full rehearsal
• Your study time follows the published SY0-701 domain weights, not the chapter order
• Every topic is practical — how attacks happen and how defenders stop them
• White-hat only: everything is taught for defense, education and legal, ethical use

WHAT YOU'LL LEARN
• Foundations — the CIA triad, threat actors and how defenders think
• Network security — protocols, firewalls, segmentation, VPNs and scanning
• Attacks and threats — phishing, social engineering, malware and web vulnerabilities
• Cryptography and PKI — encryption, hashing and digital certificates
• Identity and access — passwords, multi-factor authentication and access management
• Security operations — incident response, endpoint detection and monitoring
• Linux essentials for defenders and the ethical hacking concepts behind penetration testing
• 76 courses and 300+ bite-sized lessons in total

SECURITY+ EXAM PREP (SY0-701)
• Practice questions in the official objective order, 1.0 through 5.0
• PBQ practice — performance-based questions for every objective
• Mock exams — timed practice tests with a per-domain score report
• Exam rehearsal — full-length and timed, with flag-for-review and a breakdown of where your time went
• Readiness tracking — a predicted score on the 100–900 scale against the 750 pass line
• Quiz practice with the reasoning after each answer, plus a question of the day
• Spaced-repetition review, objective sprints and a brain-dump recall drill
• Commute mode — questions read aloud, answer with one tap
• AI PBQ forge — fresh PBQs aimed at your weakest domain (Pro)
• AI viva — an oral-exam style check that probes your answers (Pro)

HANDS-ON PRACTICE
• Labs — step-by-step missions in a simulated environment, with hints when you get stuck; the best warm-up for performance-based questions
• Security basics — a seven-day starter path: spot the phishing message, myth or fact, a password check-up and more
• AI mentor — ask about any objective, term or pair of concepts you keep mixing up

STAY MOTIVATED
• Live arena rounds three times a day and head-to-head matches against other learners
• Leaderboards, streaks, daily goals and reminders
• Certificate of completion when you pass the in-app final exam
• Available in 22 languages

WHO IT'S FOR
• Complete beginners curious about cyber security and ethical hacking
• Candidates preparing for Security+ and other entry-level cybersecurity certifications
• IT professionals moving toward SOC analyst or engineer roles
