Questions

Frequently asked

What exams does PrepPlus cover?
PrepPlus covers WAEC (SSCE), NECO, NABTEB and JAMB UTME — with past questions across all SS3 subjects: Mathematics, English Language, Physics, Chemistry, Biology, Economics, Government, Literature in English, Geography, Agricultural Science, and more.
Do I need internet to study with PrepPlus?
No. Once you’ve downloaded and activated your license, all practice questions and CBT exam mode work completely offline. Internet is only needed for account setup, payment, and the AI tutor / essay grading features.
How does the ₦5,000 license work?
You pay ₦5,000 once. A license key is emailed to you within seconds of payment. Enter the key in the app to unlock everything on one device. No monthly fees, no renewals. If you change devices, contact support and we’ll transfer your license.
Can I use PrepPlus on both my phone and laptop?
The standard ₦5,000 license activates one device. You can download both the Android APK and the Windows app for free — the license unlocks one of them. Contact us at support@prepplus.com.ng if you need a dual-device arrangement.
How is AI essay grading different from just checking answers?
For theory questions, PrepPlus sends your typed answer to an AI that reads it like an examiner. It awards marks based on key points covered, gives a percentage score, and writes specific feedback — telling you exactly which points earned marks and which were missed. Far closer to human marking than a simple keyword match.
