Completing the course?

There is a definitely overlap in domains between the two exams (LFCS and LFCE) and the exam authors were not thinking of how to do training, it was not their business as they are independent. In constructing LFS201 we did pay attention to the certification exams public information about coverage. However, there are areas listed (at low weight) where it seemed unlikely that a performance-based exam could really cover in a reasonable amount of time, as time is short on an exam and there are multiple questions. We also wanted to minimize overlap between LFS201 and LFS211 as both courses are already stuffed. Certainly if you work on LFS211 before you take the LFCS exam it will only help, even if only to gain more practice with the tools learned in LFS201. The subject matter is indeed more advanced.

By design, you should not need LFS211 for LFCS. However, the more you know, and the more context you know, the better.

Let me repeat again, none of these courses are designed to be pure examination preparation courses. We do not work that way. Yes, we know there are exams and certifications that are linked this way, but this is not the LF methodology. Our goal is to help people obtain the skill set necessary to thrive in today's technology and job market, and at the same time (obviously) to supply this talent to the organizations and industries etc that are staving for competent talent in a fast moving and dynamic technological universe.
(that does sound like PR techno-babble, but it is indeed 100 percent true.)

All LF-developed exams are purely performance based; there are no multiple choice type questions, and thus learning trivia, too many details and purely descriptive stuff does not help. There are no questions like the knowledge checks that are in the course. You have to set up, or fix things, or trouble shoot real situations in finite time and you have only two hours on the exam, so don't overthink things and spend a lot of time (for exam prep, that is!) on Herculean tasks.

Furthermore, all LF exams permit a free re-take if you fail the first time, which is far from uncommon (a benefit I personally have not heard about other certification exams). So the approach is to not over-worry it, try to stay calm and the more you can to do, the better you are likely to perform on exam day, which you can view as practice day.

I hope this helps.
