My elder girl from P1 to P2 her results were very good.. OK, I've heard that once they reach P3, their results will sure to drop but not to this extend with the home tutor's help, from Band 1 drop to Band 3.. It was so unbelieveable.. And what's more, my niece with no one helps can get Band 2 for her P3 results. What's went wrong???

The story as below : -
This current tutor is able to feedback to me on every lesson ends, whether my P3 girl is good or bad.. Before exam, tutor said "Now, I've full confident with her, she is well prepared for her exams & don't have to worry for her". Ends up, it was a nightmare beginning.. Still figuring why is that so with the help from the home tutor, my girl's result drop so much??

This tutor bought a lot of assessment book which I just discovered after the exam. When my P3 girl showed no improvement on math model, tutor will buy one all in model sums for her. When my P3 girl showed no improvement on composition, tutor will buy one with the composition. Lists goes on with all the topics with all the subjects except for Chinese because my girl all along she got herself 90+ marks & so the tutor did not help on this subject much even when I feedback to the tutor that my girl's result seems to go down..

With these, I'm not really sure is my p3 girl overloaded & thus the bad results she got for her mid-year exam. Can any cotters analysis the situation & share with me? Should I change tutor? But I can't afford to employ expert tutor whom charge $30/hour..

Pls help..
