Final Theory Test (FTT) needs to be passed before you can go for Practical Traffic Police Driving Test for class 3/3a. FTT test result is validity for 2 years and it cost $6.50 per attempt. Thus, you should try to pass it as soon as possible. The cheapest and fastest way to pass FTT is to register for FTT as a private candidate and study the test on your own. There is a free online official FTT handbook by Singapore Traffic Police which will be helpful for private candidate.
On the other hand, the school route will be longer and more expensive because you need to attend their theory lesson and Mock test(Interval Evaluation) before they allow you to take FTT which have waiting time of 1 – 2 months. You can check out the waiting time for FTT here. However, you will have access to school learning material like theory classes and Etrial test. In my opinion, doing the Etrial test multiple times should be more than sufficient for you to pass FTT. For those considering school route, you can check out the CDC brochure here for the content and cost.
