SmartPrepX — A Personalized Exam Preparation App

The Code Kraft designed and built SmartPrepX, a mobile exam-preparation platform that helps students study smarter and walk into their exams with confidence. From the very first login, each student gets a personalized study space matched to the subjects of their enrolled class.

The challenge

Students preparing for exams often juggle scattered notes, generic question banks, and no clear sense of where they actually stand. There was no single place to revise by topic, practice in real exam formats, work through past papers, and get honest feedback on weak areas. SmartPrepX needed to turn exam prep into a guided, personalized experience — and do it on mobile, where students actually study.

Our approach

• Built a frictionless onboarding flow that auto-matches each student to the subjects of their currently enrolled class, so the app feels personalized from the very first login.
• Structured all content by subject → chapter, giving students a clear, paced path through the syllabus.
• Designed multiple practice modes — chapter-wise MCQ and short-answer tests, full-book tests covering the entire syllabus, and real past papers.
• Created a detailed score card after every test that tracks performance over time and highlights the topics each student needs to work on.
• Implemented a flexible, tiered subscription model with payment integration, so each plan unlocks a different level of access to subjects, tests, and study material.

The solution

SmartPrepX gives every student a personalized study space from day one. Within each subject and chapter, learners can study curated MCQs and short-answer questions at their own pace, test themselves chapter by chapter, sit full-book tests across the whole syllabus, and practice with previous exam papers. After each test, a detailed score card shows exactly how they performed and where to focus next. A flexible subscription model lets students choose a plan that unlocks only the subjects, tests, and material they need — so they pay only for what they use.

The results

• Turned scattered, one-size-fits-all revision into a personalized study space matched to each student’s class.
• Gave students four ways to practice — chapter MCQ & short-answer tests, full-book tests, and past papers.
• Added performance score cards that track progress and surface weak areas after every test.
• Launched a flexible, tiered subscription so students pay only for the access they need.
