"1200 Multiple Choice Questions" for Standard & Higher Levels, 2003 With 50-100 IB Style Questions On Each Biology Topic (by Rita Ghalayini)

This book is now available for ordering through the website www.biology-books.com or by using one of the e-mail addresses shown below. This is a multiple-choice book prepared specifically for the IB syllabus. It contains more than 50 questions on each topic of IB Biology. This large number of questions on each topic means that students can test themselves on every point and corner of the topic studied. Moreover, this book strengthens the skills of students in answering paper 1 of the IB exam, which is composed completely of multiple choice questions and which contributes to 20% of the total mark for the whole exam.

For teachers, this multiple choice questions book is one of the best tools of teaching and reinforcing knowledge and understanding. Having a book like this enables the teacher to give homework and class work at the end of every topic and to test the student's strengths and weaknesses in the different parts of the chapter. It is also an excellent resource for tests, quizzes and exams.
