One tip - use sky scanner for flights. Especially if you book right now, you’ll find way cheaper flights (40k or 50k starting), but obviously luggage and layovers might not be for everyone.
I have booked accommodation inside ARU Chelmsford village.... They are charging 148 pounds per week.... Can you please tell me how much you would be paying outside?..... Bcoz more or less I have got to know from my friend that it is same.... And just asking why did you not prefer uni accommodation as people coming from far distance generally prefer being inside campus
