paramveer-cyber/SemSync ? reverse-engineered prompt

Build me a full stack student course tracker called SemSync.

I want a clean web app where a college student can sign in with Google, add their courses, and track semester wise progress in a simple way. Each course should let them set credits, a target grade, and break the grade into weighted items like quizzes, exams, assignments, labs, projects, and viva. Show the current grade and what they still need to score on the remaining work to reach their target.

Also include a task board for coursework, a calendar that mixes deadlines and course events, and a focus timer that keeps running state on the server so it survives refreshes and tab closes. Add a simple gamification system with XP, levels, streaks, and achievements when they complete focus sessions or hit goals.

I also want Google Classroom sync so users can connect their account and pull in courses or deadlines. Make the app feel polished, with theme and font controls, reminders, and account settings. If you need to, look up current docs online while building it.
