19 year old dependent child - possibility of ILR

I hope i can get help with my questions below;

I am a dependent child of a ILR holder. I am dependent upon my mother who recently gained ILR under 10 years long residency.
I first entered the uk on sep 2005 (aged 9).

My mother entered the UK as a Nurse in 2004 and has since been on work permit visa but accumulated 10 years here so she alone applied for ILR as it was under discretion due to some gaps in the work permit.

I am 19 years old now and i want to apply for ILR. I still live with my Mother at the same address , have a part time job and still dependent on my mother. I was wondering if i will be eligible to apply as a dependent child of a settled person on form SET (F) ? if possible will i also be able to apply at PEO.

Or will i have to accumulate 10 years residency on my own merits which will be September 2015 (bearing in mind that there have been some GAPS with my Mothers work permit visas over the 10 years and my visa status would be attached to hers - she has ILR now)

My worry is I have a university place for September 2015 and hopefully if i get the ILR i will qualify as home student fees and will be eligible to apply to student finance for tuition fee loan.

I have a younger sister who is 16 years old and came to the UK the same time as me but i would imagine her getting ILR wouldnt be any worry. Can she apply too using form SET (F) ?

I will really appreciate any advise.

Thank you.
