Form 4 Chemistry Questions and Answers: Free Practice Test

Prepare for the national exam in Form 4 Chemistry with 2,240 questions written from the school book, unit by unit. Practise the units you choose with every answer explained, or sit a full timed test and see honestly whether you are ready.

What you get

No question twice: You are given new questions until you have seen them all. Only then do the ones you got wrong return.
Every answer explained: A short reason with each answer, and the page of the book to read again.
A full timed test: Questions from the whole book against the clock, with no answers shown until you hand in.
An honest verdict: Ready, close or not yet, for each unit. It is only given once you have answered enough for it to mean something.

Questions students ask

Is the exam preparation really free?

Yes. Practice and the full timed test are free and stay free. You only need a free account, so that your answers and your progress are saved.

Where do the questions come from?

Every question is written from the Form 4 student book used in schools, unit by unit and lesson by lesson. Each answer shows the book page it comes from, so you can go back and read it.

Are these past exam papers?

No. These are practice questions that follow the book, not copies of past government papers. They train you on everything the book covers, so you know the material whatever is asked.

Will I see the same question again?

Not until you have been given every question in the units you chose. After that, the ones you got wrong come back first.

How do I know I am ready?

After 20 answers in a unit you get a verdict for that unit. Ready means 75 percent or more in every unit, not only a good average. The full timed test shows how you do under exam conditions.

Can I use it on my phone?

Yes. It works in the browser of any phone. There are no videos to load: a question, its choices and the explanation.

Do I have to buy a course?

No. The practice does not depend on any course. Now and then we suggest one course that fits how you are doing. You can ignore it.
