I bought a couple of Maths workbooks for one of my private tutees (KS2/11+). Although this was my first purchase from Exam Ninja, I was already familiar with the same books used for some of the other pupils, so was very satisfied with the contents. Sadly what brought my rating down to "Average" on this occasion was the shipping and delivery. Though it could have been said that the late delivery was not entirely Exam Ninja's fault, it was nevertheless very disappointing when the books did not arrive on the day after the receipt of an email notification that the package had been dispatched by the 1st class mail. Clearly a shipment by Royal Mail 1st class post no longer guarantees an over-night delivery. This delivery delay has pushed back the study schedule of the pupil by 1 week. Also, upon opening the packaging, finding a corner of one of the books bent backward was not very impressive, especially as I was supposed to have been buying a set of new books on behalf of the parents. Hope I will have a better experience next time.
