Hi, i studied Law LLB (hons) whilst still working 30hours per week in evenings. there is plenty of workload but it is managble. I used to be at Uni 3 days a week for lecture and seminars and that varied between 3 to 5 hours. However I used to put in extra 2 hours a day from monday to friday just recapping what I have been studying so i can have full weekend off which i did, i managed to do it for the course of 3 years and obtained 1st class division.
And if I can anyone can. But it's not easy. You just have to be disciplined about it.
