I am really sorry to hear about the bullying. Understandably he is apprehensive about returning to school but if any thing you should use the negative as a positive motivating experience. Year 6 goes by very quickly and normally the bullies do not make it into grammars. Success at eleven plus means that he can pull away from bad company amongst other things.
There is plenty of excellent advice on the forum of how to improve your son’s score. To sum it up here, your son needs to shine in one of two exams in October. These exams between them contain 21 types of questions which you can find listed here:

You can see examples of these questions here (by clicking on the demo for CD1):
Your son has to first master these 21 types of questions.
If he is struggling with any of these question types you should work through IPS method and technique book:
Once you have the techniques under the belt you need to build up speed and vocabulary. He will need a vocabulary of around 2,500-3,000 words for success. This comes from practice papers, which should include-

If your son prefers to work on computers then you can do a lot worse than verbal reasoning CD Volume 1 or Volume 3. These are written by The Tutors who teach in Wirral but share the same exam structure as us in Bucks. CD 1 give him 50 practice questions in each type of question and CD3 gives him 12 papers of 100 questions. Although the actual exam is fewer questions, each test here contains all 21 types of questions. The clock will help him focus. The link for CDs is:
There are two excellent vocabularly lists in the free section which you must print out too:

This sounds like a lot to take in, but it can be done.
Final tip: On the fridge keep a list of all 21 types, as he masters each one cross it off. This is a great motivator. Often it is easy to keep worrying about one particular question type or another and loose sight of the fact that he has made progress in tackling 90% of the types. Remember it is a multiple choice exam, so if by the end of the preparation he has to guess a couple of questions he still will stand a very good chance of success.
Best of luck.
