Getting into uni?

You've really made it hard for yourself to get into university, not only by taking a mix of of A-levels and BTECs, but also by picking such soft subjects - psychology is the only one which is even remotely respectable, the other two are worse than useless if you want to get into university. Your best bet is probably to look into some sort of foundation courses or possibly the higher level apprenticeships, and then try to get into a degree course after that. You will struggle without maths or physics, mind you, as both subjects are fairly fundamental to surveying.

I would suggest that you look at the RICS website http://www.rics.org/uk/the-profession/ which tells you how to get into the profession, what you need to study and where, what the various pathways are, etc.

For better job opportunities, you should opt for degree courses rather than diploma and also in one of the good universities like: Lovely Professional University, Thapar, Osmania, PEC, BITS...... You'll find good placements and good infrastructure here. Just find out various courses offered and eligibility criteria from their websites....
