Waheguru Ji Ka Khalsa, Waheguru Ji ki Fateh
Thanks for you kind wishes and I hope you'll surely get Admission in AIEEE. Just Trust upon yourself and give your best. Yeah I visited that Site ..IT was nice. I remeber there is one more college for Sikh Students in Karnataka (I think so i am right..but not sure).
anway if I dont know about your boards much ..SO i cant say much about this..
www.mathguru.com and www.smartclassonline.com these are two fantastic sites for science. In Mathguru, you need to register and then you can study mathematics from there. Its fantastic. Its free site.. There is written that Rs. 999/- subscription but you can register there without paying a single penny. Just Register there and you'll surely get some interesting Lectures.
Now Comes to www.smartclassonline.com this is also a very good site for studying science with interactive ways and also it clears the confusions and doubts with the three dimensional view of some things (like Van De Graff Generator, Solid State (voids etc)... so much is there.. just go and grab the oportunity..
another site is www.hellochampion.com its also meant for the students preparing for competitive exams.
