BMAT Test Physics Tips

Here are three tips to help you excel in the physics section of the BMAT:

• Review basic concepts: The physics section of the BMAT test basic concepts in physics, so it's essential to review these concepts before the exam. Topics such as forces, motion, energy, and waves are crucial and should be thoroughly understood.
• Practise with sample questions: To get a better understanding of the types of questions that will be asked, practice with sample questions. This will also help you identify areas where you need to improve. You can use sites like BlackStone Tutors for this.
• Pay attention to units: Paying attention to units is essential in physics. Make sure you understand the units used in the exam and know how to convert between them.
