Express Entry - CRS still low for ITA

[andreaia]

Thank you in advance for your help.

Came to Canada as an International Student in 2012.
Studied General Sciences for 1 year (full time)
Studied Medical Office Administration for 2 years (full time)
(Both colleges officially recognized)
Worked part-time for 8 months (in my field of study)
Currently working Full Time for 2 years and 2 months (in my field of study)
CELPIP Score: L: 11 - R: 9 - W: 9 - S: 8.
Already took TEF (basic French) hoping to get a couple points out of this.

CURRENT CRS OVERALL SCORE: 433.
PGWP expires November 2nd.

I am planning on taking a new CELPIP test to improve my Speaking score.

Human Capital - Age: 110
Human Capital - Level of Education: 98
Human Capital - First Official Language: 119
Human Capital - Canadian Work Experience: 53
Skill Transferability - Education: 38
CRS - Canadian Education: 15

What other options (besides taking a new CELPIP test) do I have to improve my CRS score? Or;
How can I extend my stay in Canada in order to have more time to improve my CRS?
I do not have an LMIA.

Your help is greatly appreciated.

If you really want to stay in Canada then push yourself to obtain CLB 9 in either the CELPIP or the IETLS, you have a guaranteed ITA by doing this.
