This is Phase 2. After exploring Schedule Pairs, you’ll use Decision Slots to handle conflicts.

The Problem: Selection Fatigue#

Planning breaks down quickly when courses have internal options.

If Course A has 3 exercise groups and Course B has 4, there are already 12 different ways those choices can interact. Add a third course, and the number grows fast.

Manually comparing these combinations, toggling calendars, remembering conflicts, trying to keep track of what you’ve already checked, is tedious and error-prone.

From Options to Concrete Schedules#

At this stage of planning, you’re no longer asking:

“What options exist?”

You’re asking:

“Which concrete schedules actually work?”

A Schedule Pair answers that question.

It represents one complete timetable choice: a specific selection of study groups, one from each block, across the courses in your Plan.

What Schedule Pairs Do#

Given a Plan, the Schedule Pairs engine:

  • takes your current partition (how study groups are grouped into blocks),
  • generates all valid combinations by selecting exactly one study group from each block, per course,
  • and ranks those combinations by how well they fit together.

Blocks come from your current partition. By default, Sisukas groups study groups by lecture / exercise / exam, but this grouping is only a suggestion. You can define your own.

Example: CS-A1110 + MATH-A1020#

Using the default partition, each course typically has:

  • a Lecture Block (often only one study group),
  • and an Exercise Block (multiple study groups).

Each Schedule Pair below represents a complete, concrete timetable choice: one study group per block, per course.

Schedule Pair 1#

  • CS Lecture (Mon 10–12)
  • CS Exercise H01 (Tue 14–16)
  • MATH Lecture (Tue 10–12)
  • MATH Exercise H01 (Mon 10–12)

→ 2-hour overlap
(CS Lecture and MATH Exercise both scheduled Mon 10–12)

Schedule Pair 2#

  • CS Lecture (Mon 10–12)
  • CS Exercise H01 (Tue 14–16)
  • MATH Lecture (Tue 10–12)
  • MATH Exercise H02 (Wed 10–12)

→ No overlap

Ranking by “Fit”#

Not all conflicts are equally bad.

The system ranks Schedule Pairs using a Fit Score, so you see the most workable options first:

  1. Perfect Fit
    No time conflicts.

  2. Manageable Fit
    Overlaps exist only in study groups marked as “recordings available”.

  3. Hard Conflict
    Overlapping exams or mandatory sessions.

Instead of silently picking one schedule for you, Sisukas shows you the ranked options so you can decide which trade-offs you’re willing to accept.

Why This Matters for Planning#

  • Without Schedule Pairs:
    You manually compare combinations, relying on memory and repeated checks.

  • With Schedule Pairs:
    The system presents the viable schedules, ordered by how well they fit, so you can focus on making a decision, not finding the options.

Schedule Pairs don’t choose for you.
They make the trade-offs visible so you can choose consciously.

Next Steps#

For any remaining conflicts, use Decision Slots to explicitly decide what you’ll attend and what you’ll skip.
