Ok listen to me carefully...
If you want the computer numbe rthe shortcut is this....
For PPL one doesn't require Math+Physics at 10+2...
Take your ICAO PPL and tell them you want to appear for PPL exams... and get a computer number for PPL, which of course is same computer numbe you will need for CPL or ATPL...
Now before you actually appear for the CPL exam you need to get some 10+2 PHY and MATH before you put in application for the Exam.
Enjoy
