which books to read???

hi I really need some recommendation please. If I take the entrance exams for medical school, which books shall I start reading to gain knowledge in biology, chemistry and pshysics? I have absolulelty NO background in science subjects as in secondary school we were not taught any of these subjects unfortunately so I really want to learn from basics but also to pass the entrance medical exam this year or next year. 1. which books are simple to understand and explain all the basics and what is needed for the exams? I cannot afford to pay much at the moment so something not expensive if you know I could order online or if anyone selling any good books. My level is absolutely beginner
