Preparing for Excellence...
We have recently migrated this portal from React JS to Next.js, and the setup is currently under migration. If you are experiencing any technical issues (e.g., while giving mock tests), please use the old portal: https://mathemsolvex.vercel.app/
If you have suggestions or want to help with the process, please contact the developer via LinkedIn: Vivek Kumar or WhatsApp: +91 9354368207. We are working hard to help you out. Best of luck!
