HiI found ex288 v. 4.6 and 4.10 has the same questions and pattern. Then wat is the difference in booking between these version.
There may be minor differences in the course contents between v4.6 & 4.10 but the main difference is OCP versions are different. You can opt for v 4.12 - that is the latest one and have significant difference compared to v4.6.
