What's new

A round of improvements to billing and learning, many of them straight from your reports.

What's new

• Fix a failed payment yourself. If a renewal payment fails, you'll see a notice on your subscription page. Pay with another card (we'll keep it for future renewals) or cancel your plan yourself, no email needed.
• No accidental second plan. If you already have an active plan or lifetime access, checkout won't start another subscription.
• Completed lessons stay completed. Revisiting a lesson you've finished no longer moves it back to in progress.
• Training corrections. We fixed 12 training questions you reported, including answer keys, explanations, edge cases, and test cases.

Manage your plan anytime at myntbit.com/subscription.

The Foundation track of the Learn path is complete. All 10 courses are now live for Premium members, taking you from mental math to derivatives and options in nearly 2,000 bite-sized lessons.

What's new

• All 10 Foundation courses. Arithmetic & Mental Math, Algebra & Precalculus Review, Single Variable Calculus, Introduction to Probability, Multivariable Calculus, Linear Algebra, Probability Theory, Statistics Fundamentals, Data Structures & Algorithms in Python, and Derivatives & Options Basics.
• Practice as you read. Quick checks inside lessons, with hints and an "I don't know" option when you're stuck.
• More ways to answer. Short answer, fill in the blank, matching, ordering, and multi-select questions, alongside multiple choice and true or false.
• Interactive exercises. Hands-on visual exercises in courses like Linear Algebra and Arithmetic & Mental Math.
• Coding exercises in Python. Write and run code right inside your lessons.
• A cleaner lesson reader. A course outline next to your lesson, unit and module overviews, and next and previous buttons that stay in reach.

By the numbers

• 1,700+ practice questions across 143 modules.
• 76 Python coding exercises and 20 interactive exercises.
• About 230 hours of learning.

We've shipped the biggest visual and UX overhaul in MyntBit's history. Every surface (landing, learn, games, training, dashboard) has been rebuilt from the ground up.

What's new

• New brand and design system. Refreshed color, type, and a locked typography scale (mono for H1, eyebrows, and numerics; sans for body) so every page feels like the same product.
• Redesigned landing, learn, and games pages with a new header, a 4-column Notion-style footer, and a restructured nav.
• New /dashboard with a sidebar shell, header, and a built-in training IDE. Your home base for daily prep.
• Training pages, rebuilt. Public /training/[slug] got new chrome, related-question discovery, and IDE polish (cleaner editor, faster scroll, better hover).
• New role pages under /tracks/ for Developer, Researcher, and Trader, plus dedicated Jobs and Enterprise pages.
• Mobile polish across the entire site: nav, hero, pricing, training, dashboard.
• Faster everywhere. SSR'd the promo banner to eliminate 0.12 CLS on every page, swept broken links, and rebuilt the perf baseline.
• Cleaner auth visuals, a new banner system, and a fresh OG image so links look sharp wherever you share them.

Library growth

• Question count bumped to 1000+ site-wide, with 400+ free.

Same MyntBit, sharper everywhere. Jump in at myntbit.com/dashboard.
