As per you query no special book is necessary for IMUCET preparation other than NCERT. You should have good command over your Class 11 and class 12 PCM and you may read a newspaper daily to do your GK part well and for the aptitude part you can use the internet and attempt mocks and for English grammar keep learning new words and their synonyms , antonyms . I would say  a bit of JEE preparation will help you fetch a decent rank.
All the best for your preparations.
