sincere advise: don't force the application if you cannot make the required points, You'll just waste money. The best thing you can do is get sideline jobs, as they can also be credited as part of your salary. Or, get an MBA - I think that's addtional 10 pts.
If I remember correctly, you need PHP 150,000 monthly to get the 45 points.
So, 45 salary, 30 college, 5 age, 10 english, 10 maintenance.
