Which extra-time multipliers can I use?

×1.25, ×1.5, ×1.75, ×2, ×2.5 and ×3. Each multiplies the student's working time.

Does extra time lengthen the break?

No. The 10-minute break between sections stays 10 minutes at every multiplier.

Where do I set a student's extra time?

On the student's accommodation settings, so every mock uses it. You can also set it per student in the lobby, or in the console during the mock as long as the student has not handed in.

How does extra time work in a scheduled mock?

Each student's clock runs from when they press Start, with their own multiplier, so a student with extra time always gets their full time.

Extra time and accommodations in class mocks

A student with ×1.5 time who sits a mock at standard time is practising for a test they will not take. Getting accommodations right is what makes their mock worth sitting.

Updated 4 October 2026 · 4 min read · from the team behind Colorbook, a free digital SAT practice tool.

In a Colorbook class mock, extra time multiplies a student's working time; the break between sections stays 10 minutes. The multipliers available are ×1.25, ×1.5, ×1.75, ×2, ×2.5 and ×3. This guide covers where to set it, how it behaves in each kind of mock, and the exact timings.

Module times at each extra-time multiplier on a full SAT-shaped paper. The 10-minute break does not change.

What gets multiplied

On a full SAT-shaped paper at standard time there are four modules: two Reading and Writing modules of 32 minutes each and two Math modules of 35 minutes each, with a 10-minute break between the sections. That is 2 hours 14 minutes of working time.

A multiplier applies to the working time only. A student on ×1.5 gets 48 minutes per Reading and Writing module and 52½ minutes per Math module, but the same 10-minute break as everyone else.

The full timing table

Time	R&W module	Math module	Working time	With break
Standard	32 min	35 min	2 h 14 min	2 h 24 min
×1.25	40 min	43¾ min	2 h 47½ min	2 h 57½ min
×1.5	48 min	52½ min	3 h 21 min	3 h 31 min
×1.75	56 min	61¼ min	3 h 54½ min	4 h 4½ min
×2	64 min	70 min	4 h 28 min	4 h 38 min
×2.5	80 min	87½ min	5 h 35 min	5 h 45 min
×3	96 min	105 min	6 h 42 min	6 h 52 min

For an English-only or Math-only paper there is no break: just double the module time in the table. A ×2 student on a Math-only paper has 140 minutes.

Where to set extra time

1. On the student's accommodation settings

This is the normal place. Set the multiplier once, on the student's accommodations, and every class mock they sit uses it. It is the best option because it does not depend on anyone remembering on the day.

2. Per student, in the lobby or the console

You can also set extra time for one student in the lobby before a mock starts, or in the console while it runs, as long as that student has not handed in. Use this for a one-off: a student whose accommodation was approved last week and not yet entered, or a mock where you want to try a different timing deliberately.

Be careful with the second case. If a student is approved for ×1.5, a mock at ×2 is generous practice but gives a misleading picture of their pacing.

How it behaves in each kind of mock

Started together from the lobby

Everyone starts at the same moment after the 3-2-1 countdown, and each student's clock runs for their own working time. Students with extra time finish later. In the proctor console each card shows that student's own time left, while the large countdown shows standard time.

Scheduled, with a start window

In a scheduled mock each student starts it themselves within the window, and their clock runs from their own Start, with their own multiplier. A ×2 student who starts at 9:30 on Saturday has the full 4 hours 28 minutes of working time from 9:30, however late the window closes.

Point this out to students with extra time. If the window opens at 9:00 and they plan to start at 15:00, they should know how late they will be finishing.

A worked example

A class of 12 sits a full SAT-shaped paper from the lobby at 9:00. Ten students are on standard time, one on ×1.5 and one on ×2. Not counting time spent getting started, the standard-time students finish at about 11:24, the ×1.5 student at about 12:31, and the ×2 student at about 13:38. If the room is only booked until noon, two students cannot finish; that is a problem to solve the week before, not on the day.

What to watch for

Book the room for the longest timing. Work out the latest finish time in the class before choosing a start time.
Ending early hands everyone in. The console's End & hand in all submits every open paper, including those of students still within their extra time. See the exam-day checklist.
Breaks inside long sittings. Only the one 10-minute break between sections is built in. At ×2.5 or ×3 a single section runs for well over two hours, so talk to the student, and whoever approved the accommodation, about how they will manage that on the real test, and rehearse it.
Read pacing against their own clock. When you look at a ×1.5 student's replay, judge time per question against their time, not the class's.
