IIT Bombay does not recommend any books for UCEED preparation. UCEED is a design aptitude test. Except for the 'Environmental and social awareness' which will evaluate your general awareness, the remaining five sections will test your aptitude.  However, a plethora of UCEED study materials are available in the market. For better understanding, compare at least 2-3 books and check the year of publication and author before you purchase the UCEED preparation books.
