The chart
Cumulative XP against completed tasks. The line is coloured by how well each task’s topic is remembered, and every course you started is a marker on it: hover for when, click to go there. Scroll or pinch to zoom in on a stretch of tasks, shift-drag to slide along it, and double-click to see them all again.
The mountain
The same tasks, as stone. Each task is one step and its top is your cumulative XP, so the stair climbs exactly as your XP did. Fit to screen shows the whole mountain; the summit is your last task.
The toolbar
The same as the graph: upload your export, filter by course (the mountain is rebuilt from just those tasks), pick a look, switch between chart and mountain, show memory levels, share a link, or design and print it.
What am I looking at in the 3D view?
- The stair. Every task is one stone step, and its top is your cumulative XP. The stair winds up a mountain and the summit is your last task.
- Gateways. A gateway stands across the stair where each course begins, with the course’s name cut into it.
- Rest paths. Where you took two or more days off, the stair gives way to a flat path of earth and grass. The longer the break, the longer the path (up to a point).
- Bridges. A placement is where you find out what you already know, so you cross a small wooden footbridge over a ravine to reach it. The more the placement credited, the longer the bridge: a short hop for no XP, a long span for a lot. Nothing ever breaks, and everyone crosses.
- Looking around. Drag to look around; double-click to look straight ahead again. Space plays and pauses, and Fit to screen shows the whole mountain.
What is the topographic map?
The contour-rings button (or 5) swaps the summary chart for a topographic map of your mountain, seen from above, and swaps back. Each course has its own stretch of altitude, from where you started it to where you started the next, and the map draws a contour line at each of those boundaries, named for the course it opens. There is a contour for every task: each task is its own thin ring of the mountain, and the ground is coloured in task by task as the replay climbs. Each ring takes the memory colour of its task’s topic, from Fresh to Locked in, the same colours as the line chart, and changes as that topic is practised again, so by the end the whole mountain shows where each topic stands. The ground still ahead is only a faint tint. Zoom in and the rings separate into lines. Point at a contour to see its task and click it to move the replay there. The route is traced on it in the memory colours of its steps, with each course where it began; click or drag along it to move the replay too. Scroll (or pinch) to zoom the map in and out, drag empty ground to move it, and double-click to fit it to the page again.
With the map on, the 2D / 3D button switches to a relief: a miniature of the mountain on a table, with the same contour for every task and the same memory colours, coloured in as the replay climbs. Drag to turn it, scroll to zoom, right-drag (or shift-drag) to move it, and click any contour to go to its task. The white lines are the courses’ own contours. Press the map button again to go back to the stair mountain.
Beside the map, under the title, is the climb by course. Its three sections share the space, so switch between them with the buttons above the figures:
- Breakdown. Tasks, XP and estimated hours by type (lessons, reviews, quizzes, multistep tasks and placements), and how many reviews you did for every lesson.
- Task. For each course, the share of each type of task. Wide blue means mostly lessons; wide orange, mostly reviews.
- Memory. For each course, how the topics you first practised in it are remembered now, from Locked in to Fresh.
When do the sounds play?
Sound is off until you turn it on with the speaker button. It plays only while the replay is playing, so scrubbing, switching view or resuming stays quiet. It follows how far up the climb you are, not how fast the replay runs, so 1× and 64× sound the same.
- Wind. Calm at the foot, and a step stronger at every fifth of the climb. Crossing into a stronger fifth brings one long gust. Flying out to the whole mountain, and back in, brings another.
- Birds and rustling pines. In the lower part of the climb (roughly the first 40%, by day). They are more frequent on a rest path, where there is grass around you.
- Crickets. Late in the climb, as the day ends (from about 60% to 90%), a little more on a rest path.
- Gateways. Climbing through one rings a rising phrase of bells, on a note of its own for each course. Walking back down through one rings a lighter, falling phrase.
- The summit. When the climb ends, a swell, a few rising notes as the topics light up, and a settling chord.
Where do the numbers come from?
Everything comes from the tasks in your export. Time answering and XP per minute are estimates (the time between a task’s start and finish, capped at 30 minutes, scaled to approximate time spent answering), the same as on the graph page. The export does not say which courses you finished, so courses mark where you first practised them. Course totals come from the course lists saved in your export, as of the day you made it, so export again to pick up changes to a course. The memory levels are Math Academy’s own at the end of the climb and the replay’s estimate before it. On the mountain one XP is worth the same height everywhere, and the summit is always the same height, so everyone’s mountain is full size.
Why is my course not at 100% when I have finished it?
A course’s progress is the topics in its list that have at least one task in your history, out of every topic on that list. The list is the one saved in your export, so it can run ahead of what you did: Math Academy adds topics to courses over time, and one you finished a while ago may have grown since. Topics can also be credited without a task of their own, for example when you pass a more advanced topic and Math Academy counts the ones it builds on. Neither shows up as a task, so those topics stay uncounted.
Why is my topic count not the same as Math Academy’s course page?
The totals here come from the course lists in your export, not from the live course page. Math Academy revises its courses (topics are added, moved or removed), so the live page can list more or fewer topics than the course had when your export was made. A topic shared by several courses is counted once when you show more than one. Export again to pick up the latest course lists.
