Hello,
I actually did the same subjects as you and graduated last year with 97.95. I did 7 subjects with the extra 2 being further and specialist. Since you aren't planning on doing specialist, I would recommend further. Although further scales down, I believe if you do good for methods, english and chinese SL it is highly likely you can get 95+ (I got 40+ for english and chinese SL, the rest were mid 30s).
