ICSE Class 10 Biology Practice Paper 2023 for Last Minute Preparation

ICSE Class 10 Biology Practice Paper 2023: The Class 10th ICSE board Biology paper is going to be held on 29 March 2023. This is the right time to take a look at important practice questions and increase your chances of scoring good marks in the exam. ICSE Class 10 Biology is Paper 3 of the Science course (Code: 52). It’s comparatively easier than Chemistry and Physics, but due to the advanced syllabus of the CISCE board, Biology is much tougher than it appears. Students should take it seriously and study with dedication. An effective way to succeed in biology is by practising important questions before the exam. We have prepared an ICSE Class 10 Biology practice paper consisting of crucial questions for last minute revision before the exam.
