The online assessment is the same exam for either the 2394 or 2395 (so you do not have to do it twice).
The course you are taking should cover all the information you need to pass the exams.
So so long as you have been paying attention(!) you should be fine.
The way the questions are worded can be very confusing and you have to learn C&Gspeak!
Read all the question and try and break it down if you can into the specifics of what they are asking.
e.g if it says new installation, you know that the installation has never been energised and that everything will meet the current regulations.
If it mentions a cable type or description then that is the cable you are using to answer the question.
You can get information on the exam structure and a fair amount of detail on the requirements of the exams from the
city and guilds website and their course handbook (in the documents tab, centre documents). You can also read the Chief examiners reports to aid you in areas of common failure (in additional documents).
The break down of the on line exam is as follows:
Unit 301 (Online Multiple Choice): Duration: 1 hour 20 minutes
1 Understand the requirements for completing the safe isolation of electrical circuits and installations
7 questions 18%
2 Understand the requirements for initial verification of electrical installations

5 Understand the requirements for testing before circuits are energised

Easy really, good luck.
