Assalam O Alaikum! lets talk about books for issb prepration. Many books are available in market like Carvaan, Dogar publishers etc. Carvaan publishers are much better than others. But remember it is not a chemistry or physics test that you can prepare it from any helping book and copy from it. Remember books are just for your guideline and these books only provide you practice material. It's not necessary that you have to learn the sentences from that book. Psychologists and other officers that are present at issb center to judge you are quite experienced and they can judge you within second that you have written sentences by yourself or have prepared or learnt from any helping book. Simply ISSB is your personality test and materials books have is just for your guideline and sentences, stories are not according to your personality. The writers have just written for your guideline. Morever, books are not updated on regular basis . So, you must take info regarding changes in issb from the candidates those who have recently undegone issb test. With the passage of time, many changes take place. For example: screen out test has been replaced by OPI test since last year but books still contain Screen out details.So, kindly be in contact with the people who are recenntly preparing ISSB or recently have undergone issb test. So you may know how to prepare smartly for issb. It's not the way that you purchase many books. Just purchase any book like carvan or dogar publishers and start practising different tests held at issb. Cover up your mistake and don,t go for mass collection of book. It will just ruin your time nothing else. Just purchase a book although they are also present online in pdf format and focuses more on your self prepration. May ALLAH ALMIGHTY be your Guide Ameen.
