"I'd been staring at the same graph problem for three days. Marcus walked me through it in 40 minutes and I immediately solved the next five on my own."
Went from failing LeetCode mediums to landing a Google internship in 8 weeks.
Ryan Kowalski
Career switcher, former accountant
"I was grinding LeetCode at midnight, getting nowhere. Three sessions with Marcus and I finally understood why recursion actually works."

Questions we actually get.
Not the ones we wish you'd ask.
Yes. Before your first session, we ask for your course number, textbook, and any relevant assignments. Your tutor has either TAed, taken, or tutored that exact course at multiple universities. They'll speak your professor's language.
Absolutely not. About 30% of our students are career switchers. Our tutors have coached people from accounting, nursing, and military backgrounds into SWE roles. The quiz just finds your current level — wherever that is, we start there.
Most students need 3–6 sessions to close a specific gap. After your free session, your tutor will give you a concrete assessment: what to fix, how long it'll take, and whether you need them at all or can finish with the resources they'll give you.
Discord and Stack Overflow fix the symptom (your specific bug). We fix the cause (the conceptual gap that produced the bug). You won't ask the same category of question twice.
Yes. About 15% of our students are AP CS or pre-college. We adjust the pace and analogies accordingly. Parents book the first session; after that, most students continue on their own.
Your tutor reviews your quiz results, asks you to walk them through your current problem out loud, and then works through it with you — not for you. You'll leave with a fixed bug AND an explanation of why it broke. The session is 50 minutes.
