Take the Class 1 medical as without it you cannot move on to ATPL studies.
Once you have the initial medical done it will also act as a Class 2. You can let the Class 1 part lapse until you need to renew it for your CPL flying training.
In the long run this may work out cheaper than getting an initial Class 2 now followed by an initial Class 1 later.
Good Luck
