The OLODE exams

I’m sorta new to this and I’m studying for the dgca exams rn and all ik about the olode exams are that they’re online. Questions: 1) Are they the same as the normal exams or is there a diff in significance? 2) Does it make any diff if i give normal or OLODE except the mode of exam? 3) I heard smone saying they’re much tougher than the written papers, hence why this person is not attempting any OLODE papers. Facts?
