Science tutoring that shows you the gaps.
Small-group GCSE and A-level science with a tutor who knows the specification. Every topic sits on a map that turns green, amber or red as your child practises, so you can both see what's secure and what still needs work.

1.4 Power & Efficiency
AQA · HigherWhat you need to know · 8 points
Define power as the rate of energy transfer; 1 W = 1 J/s
Use P = E / t and P = W / t
Learn this equation
Use efficiency = useful energy out ÷ total energy in
Learn this equation
Describe ways to increase the efficiency of an energy transfer
Exam trap: efficiency can never be more than 1 (100%). Check your answer.
How it works
- 1
A free diagnostic
We find out where your child actually is on their own exam board's specification, not a generic test.
- 2
Small-group lessons
Up to four students with a real tutor. After each lesson, ten homework questions on exactly what was just taught.
- 3
Practice that fills in the map
Short practice quizzes turn each topic green, amber or red. Shaky topics come back sooner so they don't slip.
- 4
A weekly report for you
A private link to your child's report: what they practised this week, how they did, and where the gaps still are. It updates itself, so bookmark it.
Only what their exam asks for
Every GCSE Biology, Chemistry and Physics topic has a checklist of what to know, filtered three ways. We also teach A-level Physics (AQA).
Their exam board
AQA, Edexcel or Cambridge IGCSE. The topic map and every checklist follow that board's specification.
Combined or Triple
Combined Science students never see Triple-only topics, so no time goes on content they won't be examined on.
Foundation or Higher
Higher-only points appear only for Higher students (on Cambridge, Core or Extended).
How we compare
| What you get | One-to-one tutor | Revision apps | EPL Tutors |
|---|---|---|---|
| A real teacher in a small group | Yes | No | Yes — 4 students max |

Questions parents ask
GCSE Combined or Triple Science, and A-level Physics. Groups are capped at four so the teaching stays close.
