Quiz tematyczny 1: Logical formulas: IF, IFS, AND and OR

  1. Pytanie 1 z 15

    What does =AND(5>3, 2>4) return?
    Pokaż odpowiedź

    Odpowiedź: B. FALSE

    AND returns TRUE only when every test is TRUE. 2>4 is FALSE, so the result is FALSE.

  2. Pytanie 2 z 15

    What does =OR(5>8, 3<4) return?
    Pokaż odpowiedź

    Odpowiedź: D. TRUE

    OR returns TRUE when at least one test is TRUE. 3<4 is TRUE, so the result is TRUE.

  3. Pytanie 3 z 15

    In the sheet below, what does =NOT(D3="South") return?
    ABCD
    1NameSalesAccountsRegion
    2Ana5200014North
    3Ben4750022South
    4Chloé610009North
    5Dev3900018East
    6Eli5800025South
    7Fatima4500011East
    Pokaż odpowiedź

    Odpowiedź: B. FALSE

    D3 holds South, so D3="South" is TRUE. NOT reverses it, so the result is FALSE.

  4. Pytanie 4 z 15

    In the sheet below, E2 contains =IF(AND(B2>=50000,C2>=12),"Bonus","No bonus") and is copied down to E7. How many cells show "Bonus"?
    ABCD
    1NameSalesAccountsRegion
    2Ana5200014North
    3Ben4750022South
    4Chloé610009North
    5Dev3900018East
    6Eli5800025South
    7Fatima4500011East
    Pokaż odpowiedź

    Odpowiedź: B. 2

    Both tests must be TRUE. Only Ana (52,000 and 14) and Eli (58,000 and 25) pass both.

  5. Pytanie 5 z 15

    In the sheet below, E2 contains =IF(OR(B2>=50000,C2>=20),"Bonus","No bonus") and is copied down to E7. How many cells show "Bonus"?
    ABCD
    1NameSalesAccountsRegion
    2Ana5200014North
    3Ben4750022South
    4Chloé610009North
    5Dev3900018East
    6Eli5800025South
    7Fatima4500011East
    Pokaż odpowiedź

    Odpowiedź: C. 4

    OR needs just one TRUE test. Ana, Chloé and Eli pass on sales, and Ben passes on accounts (22), so 4 people get "Bonus".

  6. Pytanie 6 z 15

    What must you put around text such as North when you use it inside a formula like =IF(D2="North","Yes","No")?
    Pokaż odpowiedź

    Odpowiedź: B. Double quotation marks

    Text in a formula goes inside double quotation marks. Without them, Excel tries to read the word as a name and usually shows #NAME?.

  7. Pytanie 7 z 15

    How many conditions can you test in one IFS function?
    Pokaż odpowiedź

    Odpowiedź: A. 127

    Microsoft says IFS can test up to 127 different conditions. (AND and OR can each take up to 255.)

  8. Pytanie 8 z 15

    In the sheet below, what does =IFS(B5>=60000,"Gold",B5>=50000,"Silver") return?
    ABCD
    1NameSalesAccountsRegion
    2Ana5200014North
    3Ben4750022South
    4Chloé610009North
    5Dev3900018East
    6Eli5800025South
    7Fatima4500011East
    Pokaż odpowiedź

    Odpowiedź: C. #N/A

    Dev's sales (39,000) make neither test TRUE. When no condition in IFS is TRUE, it returns the #N/A error.

  9. Pytanie 9 z 15

    You want IFS to return "Bronze" when none of the earlier tests are TRUE. What do you put as the last test?
    Pokaż odpowiedź

    Odpowiedź: A. TRUE

    To give IFS a default result, enter TRUE as the final logical test and the default value after it.

  10. Pytanie 10 z 15

    In the sheet below, E2 contains =IFS(B2>=60000,"Gold",B2>=50000,"Silver",TRUE,"Bronze") and is copied down. What does E6 show?
    ABCD
    1NameSalesAccountsRegion
    2Ana5200014North
    3Ben4750022South
    4Chloé610009North
    5Dev3900018East
    6Eli5800025South
    7Fatima4500011East
    Pokaż odpowiedź

    Odpowiedź: C. Silver

    E6 checks Eli's 58,000. It is not 60,000 or more, but it is 50,000 or more, so IFS stops at "Silver".

  11. Pytanie 11 z 15

    In the sheet below, E4 contains =IF(B4>=50000,"Silver",IF(B4>=60000,"Gold","Bronze")). What does it show for Chloé?
    ABCD
    1NameSalesAccountsRegion
    2Ana5200014North
    3Ben4750022South
    4Chloé610009North
    5Dev3900018East
    6Eli5800025South
    7Fatima4500011East
    Pokaż odpowiedź

    Odpowiedź: D. Silver

    IF stops at the first TRUE test. 61,000 is already 50,000 or more, so "Silver" is returned and the Gold test is never reached. Put the highest tier first.

  12. Pytanie 12 z 15

    In the sheet below, E2 contains =IF(NOT(OR(D2="North",D2="South")),"Check","OK") and is copied down to E7. How many cells show "Check"?
    ABCD
    1NameSalesAccountsRegion
    2Ana5200014North
    3Ben4750022South
    4Chloé610009North
    5Dev3900018East
    6Eli5800025South
    7Fatima4500011East
    Pokaż odpowiedź

    Odpowiedź: A. 2

    OR is TRUE for North or South, and NOT flips it. Only the two East rows (Dev and Fatima) give "Check".

  13. Pytanie 13 z 15

    In the timesheet below, D2 contains =IF(B2>40,(B2-40)*C2*1.5,0). What does D2 show?
    ABC
    1NameHoursRate
    2Gus4422
    3Hana3824
    4Ivan4021
    Pokaż odpowiedź

    Odpowiedź: D. 132

    Gus worked 44 hours, which is more than 40. Overtime pay is (44-40) x 22 x 1.5 = 132.

  14. Pytanie 14 z 15

    In the timesheet below, D4 contains =IF(B4>40,(B4-40)*C4*1.5,0). What does D4 show?
    ABC
    1NameHoursRate
    2Gus4422
    3Hana3824
    4Ivan4021
    Pokaż odpowiedź

    Odpowiedź: C. 0

    Ivan worked exactly 40 hours. 40>40 is FALSE (> means strictly greater), so IF returns the value_if_false, 0.

  15. Pytanie 15 z 15

    In the sheet below, E3 contains =IF(C3>=20,IF(B3>=50000,"A","B"),"C"). What does E3 show?
    ABCD
    1NameSalesAccountsRegion
    2Ana5200014North
    3Ben4750022South
    4Chloé610009North
    5Dev3900018East
    6Eli5800025South
    7Fatima4500011East
    Pokaż odpowiedź

    Odpowiedź: A. B

    Ben has 22 accounts, so the outer test is TRUE and Excel checks the inner IF. His sales (47,500) are under 50,000, so it returns "B".

Co warto wiedzieć przed egzaminem

  • IFS can test up to 127 conditions. If none is TRUE it returns #N/A, so enter TRUE as the last test to give a default result.
  • In SUMIFS the range to add comes first, but in SUMIF it comes third. SUMIFS accepts up to 127 range/criteria pairs.
  • XLOOKUP uses an exact match by default and can return a value from a column on either side. VLOOKUP only looks from left to right.
  • IFERROR catches the #N/A, #VALUE!, #REF!, #DIV/0!, #NUM!, #NAME? and #NULL! errors.
  • Excel stores dates as serial numbers so they can be used in calculations. January 1, 1900 is serial number 1.
  • Data validation shows messages and blocks invalid entries only when people type in a cell. Copied or filled data can get past it.
  • Remove Duplicates deletes data permanently, so Microsoft suggests copying the original data to another worksheet first.
  • In a PivotTable, Count is the default summary for value fields that have text or blank cells; Sum is the default for numbers.

Najczęściej zadawane pytania

What certificate do I get, and what is it not?

If you score 80% or more on the final assessment, you can download a certificate of completion for this course. It shows you finished a general skills course. It is not an accredited qualification, not a Microsoft certification such as Microsoft Office Specialist, and not an employer or government certification.

Should I take the Excel for beginners course first?

If you are new to formulas, yes. This course assumes you can already use SUM, AVERAGE, COUNTIF, a simple IF and absolute references ($A$1).

Which version of Excel do I need?

The lessons describe Excel for Microsoft 365. XLOOKUP needs Excel for Microsoft 365 or Excel 2021 and later; it is not in Excel 2016 or 2019. IFS and TEXTJOIN need Excel 2019 or later. In older versions, use VLOOKUP or INDEX and MATCH, and nested IF.

How does the final assessment work?

It has 35 questions picked at random from the course question bank, and you have 35 minutes. Many questions show a small spreadsheet and ask what a formula returns. You get a new mix each time.

Can I practise with my own work files?

Use the practice sheets in the lessons. If you use real work data, follow your employer's policies and privacy rules, and work on a copy so you do not change the original.

Czy zaświadczenie jest akredytowane lub oficjalnie uznawane?
