I am an ESOL teacher and have students stay with me for total immersion and lessons. I bought this because I recently had a Spanish woman stay for 3 months to in order to prepare for the FCE exam. I downloaded a free sample test from the Internet but then had to print off all the pages so she could do the separate tests - it took ages to organise the printing, and I was in danger of losing vital pieces of paper. These 4 sample tests by Mark Harrison are authentically laid out, give clear instructions to the student, have the answer key AND the CD is easy to use on the computer or a CD player - what more could I want. My student could work alone or with me, and gain lots of valuable FCE experience. All for a very reasonable price - well done that man.
