LSE's school-wide latest date of registration is Friday 19 October 2018 and you will not be allowed to register after this date. However, many programmes have earlier latest dates of registration.
If you plan to arrive at LSE after your allocated registration date you must check that your department will allow this.
Your department will also let you know how best to catch up with anything that you might have missed. Depending how late you register this may include orientation activities and teaching sessions. Remember that you are not allowed to attend teaching until you have registered.
