Chemistry

How to study chemistry

Chemistry mixes memorising (names, reactions, rules) with understanding (why a reaction happens) and calculating. You need all three, and each needs a different kind of practice.

Quick overview

Business information systems collect and process the information that supports decision-making in companies.

Key takeaway: Without good data, even the best system will not produce good decisions.

Types of system

  • Transactional – captures the day-to-day business events.
  • Decision support – analysis and scenarios for management.
  • ERP – ties the processes into one data model.

Why it is hard to learn

A study plan that works

  1. Understand the concept first

    Upload the chapter or lecture and read Memo's notes, which explain the why, not only the what. Formulas and equations are written out properly.

  2. Memorise the facts with flashcards

    Reactions, functional groups, rules and definitions go on flashcards.

  3. Ask about what does not make sense

    Ask the chat on the note when a step is unclear. It explains from your own material.

  4. Practise calculations on your exercises

    Work through your teacher's problem sets as well. Memo's practice tests check the theory; calculations need practice of their own.

The study modes that fit best

Notes

For the explanations behind the rules.

Flashcards

For reactions, names and definitions.

Practice test

For written answers and explanations.

Quiz

For a quick check of the theory.

Questions

How do I remember chemical reactions?

Learn them by type, not one by one, and test yourself with flashcards that ask for the products. Understanding why a reaction happens makes it much easier to remember.
