Any tips for doing well in Junior certificate Science ?

Make sure you go over your definitions as many questions will ask you to define a key term. In Physics make sure you learn off your formulas. The exam tends to cover most of the topics so it's not a good idea to take short cuts by leaving out topics. Don't forget to go over your experiments as these always make up a big part of the exam. Practicing past exam papers is especially important in Science. Study one topic at a time and then go through that topic on Studyclix comparing your answer with the marking scheme.
