Mr ripley, thanks for a prompt response. I raised the question about roster because later in life I'd like to study another university degree (either to get a second BEng or upgrade my current BSc with an MSc; as a mature student via part-time mode of study, online/longdistance is not an option) ... How about 6 or 7 years down the line? Would I have better chances then? Or, maybe if I'd switch base or go LH?
