This book is basically a big collection of past exam papers meant for students who want to test and sharpen their science knowledge. Instead of being a regular textbook that explains concepts step by step, it’s like a giant practice ground full of real exam questions. It gives you a chance to see how actual papers are set, what kind of tricky problems appear, and how the difficulty changes over the years. It feels less like “reading a book” and more like sitting down with a whole bunch of challenges that slowly build your confidence.
