Your first week with a new subject: a plan that sticks

A simple first-week plan for any new subject, worked out for starting chemistry: vocabulary first, one example a day and a Friday self-quiz.

Updated November 12, 2026 • 4 min read

In short

The first week of a new subject feels like everyone else already knows something you do not. In chemistry the pile is words (element, compound, mixture) and symbols. You do not need to understand everything yet. You need a small routine that makes the words familiar and gives you a place to ask questions.

In short

  • Learn the vocabulary first; most early confusion is just unfamiliar words.
  • Do one worked example a day, and redo it the next day without looking.
  • End the week with a short self-quiz so you find the gaps while they are small.

The plan at a glance

  • Every day, 20 minutes: read the day's vocabulary, do one worked example, write one question.
  • Day 1 to 2: words and what they mean.
  • Day 3 to 4: use the words on a worked example.
  • Friday: a short self-quiz, from memory, then check.

Twenty minutes a day is a suggestion, not a rule. Pick an amount you will actually do.


Step by step

  1. 1. Get your word list

    Open the chapter or class notes and list every word in bold or that your teacher repeated. Aim for about ten words, not all of them. Put each on a card or a line: word on one side, meaning in your own words on the other.

  2. 2. Say each word out loud

    Say it, then say a sentence with it. Hearing yourself use the word helps more than rereading it silently.

  3. 3. Do one worked example

    Find a solved example in your book. Cover the solution, try it, and then compare. If you cannot start, read the first step only and try again.

  4. 4. Write one question

    At the end of each session, write the one thing you are least sure about. Take the list to class or a classmate.

  5. 5. Redo yesterday's example

    Start each session with five minutes redoing the previous example without looking. This is the part that moves it into memory.


Worked example: a first-week plan for starting chemistry

Here is a plan for the first week, using words that usually come first: atom, element, compound, mixture, physical change, chemical change, density.

Day

Do this

Check yourself

Mon

Learn atom, element, compound: write each in your own words

Can you say which of water, oxygen gas and gold is a compound?

Tue

Learn mixture, physical change, chemical change

Is melting ice a physical or a chemical change?

Wed

Worked example 1: density

See below

Thu

Redo Wednesday's example from scratch, then a similar one

Same steps, new numbers

Fri

Self-quiz: 10 questions from memory

Mark it and list what to review

Five days, about 20 minutes each.

Check the Tuesday and Monday answers. Water is a compound (hydrogen and oxygen joined). Oxygen gas is an element. Gold is an element. Melting ice is physical: it is still water, only a different state.

Wednesday's worked example uses the formula density = mass ÷ volume. A piece of metal has a mass of 54 g and a volume of 20 cm³. Divide: 54 ÷ 20 = 2.7, so the density is 2.7 g/cm³. Check by multiplying back: 2.7 × 20 = 54 g, which matches. On Thursday, change the numbers, for example mass 81 g and volume 30 cm³: 81 ÷ 30 = 2.7, the same value, which tells you it is probably the same metal.

On Friday, write ten questions for yourself, such as "define element in your own words" and "compute density for 54 g in 20 cm³", then answer them with the notes closed. Mark the answers, and put the ones you missed at the top of next week.


If something goes wrong

  • You do not understand a word. Look for it in your book's glossary, then ask your teacher in class. Write the question down so you do not forget it.
  • You skipped a day. Do not double up. Pick up where the plan is.
  • The worked example makes no sense. Go back one step and find the word or the earlier example you missed.
  • You score badly on Friday. That is the quiz doing its job. List what you missed and start next week there.

A note on notebooks: keep one page per day with the date, the words you learned, the example you solved and your question. After a week you have five pages that show exactly what you covered, which makes it easy to tell your teacher where you are stuck and gives you a start for revision later.

It also helps to teach the words to someone else. Explain element versus compound to a friend or family member in two sentences. If you cannot, you have found the thing to review.


Keep it going

Next week, keep the same routine and add the next ten words. Keep your cards, shuffle them, and check old ones for a minute each day. Share your list of questions with your teacher; asking shows you are paying attention.

If you want a study partner who is always there, DuckyHelper can see your screen, draw on it and work through a problem with you out loud, then quiz you if you ask. There is a 10 minute trial with no card at download.


Frequently asked questions

How long should each session be?
Short and regular beats long and rare. Twenty minutes you do every day is better than two hours once.
Should I read ahead?
A little is fine, but your first priority is understanding what you have already been taught.
