I bought the book [from http://www.homeshop18.com/instrumentation-engineering-gate-refresher-1st-edition/author:gate-academy/isbn:9788131514528/books/miscellaneous/product:25398277/cid:14567/] and in my primary review it is looking good and easy for the last week refreshment of all topics. All subjects are divided in to chapters here. The authors included 85% important theory parts and equations here. "This is not a Question Bank".
