One week with Sage

The week, planned in letters.

Before each class, your tutor writes to you with the plan for that class. After it, you get a recap.

You took 3(b) from 1 mark to 3.

Covered the trend, and comparing with numbers. Deferred explaining the plateau.

Thursday 17:30 · Class 14 · Biology

Your tutor teaches you. Live.

Paper 4 · Question 3(b)[3 marks]

Describe the effect of temperature on the rate of water loss from the upper and lower surfaces of a leaf.

Why does the lower surface lose more water?

It checks your work. Live.

Sage reads what you typed while you're still in class, and points out anything you are missing.

Your answer

Transpiration increases as temperature increases because more water evaporates from the leaf.

1/3

1 of 3. You've got the trend. Now compare the two surfaces with numbers, and say where it levels off. ‘Describe’ doesn't need the ‘because’.

Same two marks as last week.

Your rewrite, after the note

Water loss rises as temperature increases from 10 °C to about 35 °C, then levels off. The lower surface loses more water than the upper surface at every temperature, reaching 1.7 compared with 0.55 mg per cm² per hour.

3/3

3 of 3. Trend, comparison with numbers, and where it levels off.

Drill · question 3(b)30 seconds

Which description scores all 3 marks?

Then: explain the plateau in one sentence.

Still in class · from the answer you just typed

Rapid fire round.

Sage turns your mistakes into a 30-second check. Pick the one that scores all three marks.

How today's Biology class went

Here's where today left us.

You took question 3(b) from 1 mark to 3. We didn't get to explaining the plateau properly, so it's first on Thursday.

You asked why the lower surface loses more water. It has more stomata, so more water vapour can escape.

Homework: one graph description and one explanation question.

The moment it clicked

The comparison. You quoted 1.7 against 0.55 without me asking.

What we covered

  • Describing a graph: the overall trendCovered
  • Comparing two lines, with numbersCovered
  • Explaining the plateauDeferredCarried to Class 15

That sets up the next step cleanly.

Class 15 · next Thursday 17:30

Next week's lesson has already adapted.

The same mistake showed up in two separate classes? The next class is built around it.

What Sage remembers

Describing graphs: gets the trend, then drops the comparison with numbers and where the line levels off.

Seen in Class 13Photosynthesis graph, rate against light intensity. Trend right, same two marks lost.

Seen in Class 14Question 3(b), water loss from a leaf. Trend right, same two marks lost.

You can see and remove this.

FAQs

Is this a chatbot?

It's a scheduled class. Your tutor talks with you out loud, works on the same page as you, and gives feedback on your work as you go. It remembers last time and plans the next class around it.

What if I miss a class?

Your tutor sends up to three make-up times for the next week. The plan waits exactly where you left it.

Can I move a class?

Ask your tutor, in chat or on a call. “Can we do Friday instead this week?” gets “Friday 17:30 works. Same plan. Want me to move it?” Nothing changes until you say yes.

Which subjects?

Any subject you can name. Upload your syllabus, notes or past papers and the plan is built from them.

How long is a class?

You choose: 15 minutes to 2 hours, in 15-minute steps, at a fixed weekly time or week by week.

What do I need?

A browser and a mic. Nothing to install, and nobody's on camera.

How old do I need to be?

13 or older. If you're under 18, a parent or guardian needs to agree.

What happens to my data?

We never sell your data or use it to train outside AI models. You can see and remove what your tutor remembers.

We'll take it one clear step at a time.

We're on shortly. I've laid today's plan out already, so we can start straight on the first step.

What I've got planned

  • The seven life processes (MRS GREN)
  • Respiration is not breathing
  • Excretion or egestion?

Nothing to prepare. Just bring whatever you got stuck on last time.

One step at a time, as always.

Your first class is free.
