Stuck on O/A Level revision?

The Wise Otter breaks down O/A level subjects into the exact skills you need to ace exams

Meet Tessa — and see how she uses The Wise Otter.

Tessa is a secondary school student with a math test on inequalities tomorrow.

She's stuck. The clock is ticking.

"This feels so overwhelming."
The Wise OtterThen she remembers

The Wise Otter. She opens the
app and creates a study plan.

First, Otter scans the MOE syllabus to create a tailored study plan for Tessa

Otter breaks down inequalities into core concepts and organizes them into a step-by-step study plan.

Tessa starts learning. Otter breaks complex topics into smaller chunks to prevent mental overload

Each step is small enough for Tessa to follow. Every step builds on the last so Tessa understands, not just memorizes.

Otter tracks every answer and uses spaced repetition to schedule reviews at just the right time

This helps Tessa revise concepts that she's at risk of forgetting, helping her learn more in less time

The confusion fades. She smiles slightly.

"I finally get it."

How you'll actually improve (not just study more)

Most students study hard but don't see results. The Wise Otter's study mode uses learning science to turn study time into better grades

Stop forgetting what you studied last week

Move knowledge into long-term memory

Spaced repetition: Schedules reviews at scientifically optimal intervals. It's the same method medical students use to memorize thousands of facts

Active retrieval Practice: 2-3x more effective than rereading according to cognitive science

No more cramming the night before only to forget it all after the exam

Make difficult topics click

Break down complexity into manageable steps

Step-by-step scaffolding: Breaks complex topics into smaller chunks to prevent mental overload

Build understanding: Each step builds on the last—you'll understand instead of just memorizing

Handle variation: When questions are worded differently, you can still apply what you learned

Prepares you for real exam conditions

Interleaving and mixed practice to prepare you for exams

Mixed practice: Forces you to identify which method to use, just like exams where questions aren't grouped by topic

Optimised reviews: Tracks each response and uses the forgetting curve to schedule reviews just before you forget

Exam confidence: Walk into exams knowing you can handle any concept

Fix weak spots before they cost you marks

Remediation to fix weak spots before they cost you marks

Tracks struggles: Identifies which concepts you struggle with and gives you advice on what to work on

Like a personal coach: More efficient than spending equal time reviewing what you already know

Prevents gaps: Detects prerequisite gaps and fixes them before they become bigger problems
