SAT-95: Using the Scratchpad Effectively

SAT-95: Using the Scratchpad Effectively

Description: Messy scratch work creates careless errors; organized scratch work prevents them. Whether you use the digital SAT's built-in notepad or scratch paper, a few habits turn your scratchpad into a tool that earns points instead of losing them.

Habit 1 — label each problem

Write the question number next to your work so you never mix up calculations or lose track when you return to a marked question. (Oʻzbekcha: har bir ishni savol raqami bilan belgilang — chalkashmaslik uchun.)

Habit 2 — write the equation before you compute

Jotting the equation (or the formula) first forces a correct setup and gives you something to check against. Most arithmetic errors come from doing steps in your head; writing them down makes them catchable. (Oʻzbekcha: hisoblashdan oldin tenglamani yozing — bu toʻgʻri tuzilishni taʼminlaydi.)

Habit 3 — keep steps vertical and spaced

Stacking one step under the next (instead of cramming sideways) makes it easy to spot where a sign or number went wrong. Leave space; you're not saving paper. (Oʻzbekcha: qadamlarni tik va keng joylashtiring — xatoni topish oson boʻladi.)

Worked Example 1 — setup before numbers

Problem: "20% of what number is 30?" Good scratch work writes the equation first.

• Write: 0.20 × n = 30. Then solve: n = 30 ÷ 0.20 = 150.
• Because the equation is on the page, you can re-check the setup if the answer seems off.

Worked Example 2 — sketch the figure

A geometry problem describes a right triangle with legs 6 and 8 but shows no picture.

• Quickly sketch the triangle and label 6 and 8 on the legs. Seeing it, you apply 6² + 8² = c² → c = 10.
• A 10-second sketch prevents mislabeling which sides are the legs.

(Oʻzbekcha: rasm berilmagan boʻlsa, oʻzingiz chizib, tomonlarni belgilang.)

Worked Example 3 — track what you've eliminated

On a multiple-choice question you rule out A and D.

• Cross them off on the scratchpad. Now if you guess, you instantly see only B and C remain (a 50% shot — see SAT-88).

Worked Example 4 — record the units

A problem gives a speed in km/h but asks for meters per second.

• Write the units beside each number as you convert (km/h → m/s). Tracking units on paper stops the classic unit-trap (SAT-50, SAT-89) from sneaking in.

Tip: a tidy scratchpad isn't about neatness for its own sake — it's about making your own mistakes visible before they cost points. (Oʻzbekcha: tartibli qoralama — xatolarni ball yoʻqotishdan oldin koʻrinadigan qiladi.)

Digital vs paper — same principles

On the digital SAT you get an on-screen notepad, and many test centers also allow scratch paper — use whichever you find faster, but apply the same habits to both. Typing is slower for math symbols, so a quick handwritten sketch of a figure or a stacked calculation often beats the notepad for geometry. Whatever you use, the goal is identical: externalize your thinking so errors become visible. The worst scratchpad is the one in your head, where mistakes hide until they cost points. (Oʻzbekcha: raqamli yoki qogʻoz — qaysi tezroq boʻlsa, ishlating; muhimi fikrni tashqariga chiqarish.)

Practice 1

Why write the equation "0.25 × n = 15" before solving, instead of computing in your head?

Practice 2

You've eliminated two of four choices but must move on. What should your scratchpad show?

Key words — Kalit soʻzlar

• Scratchpad — qoralama (chernovik)
• Label — belgilash (nomlash)
• Setup — tuzilish (tayyorlash)
• Sketch — chizma (eskiz)
• Step — qadam
• Cross off — chizib tashlash
• Units — oʻlchov birliklari
• Organized — tartibli
• Re-check — qayta tekshirish

Summary

• Label each problem, and write the equation/formula before computing.
• Keep steps vertical and spaced so errors are easy to spot.
• Sketch missing figures, track units, and cross off eliminated choices.
