Take manual.
I just passed my driving test about a month ago. Total takes about 9 months as I only go for my driving on Mondays and sometimes Mondays + Wednesday / Friday.
I learned at BBDC with fixed instructor and it can be faster if I have the time to cramp my practical lessons and time to study my BTT and FTT. The thing which drags me is my FTT as I forget to book 2 months before my last practical lesson aka 5.1. In the end, I have to wait till I come back from China holidays then take my TP test.
I suggest that you cramp your lessons if you want to complete within 6 months. 3 practical lessons per week plus 3 more practice lessons after your 5.1. So to complete about 25 lessons, you will need 2.5 months. During the mist of taking your practical, fork out your saturday mornings for theory lessons and tests. Try to complete your Basic Theory lessons and Test within the first month, then proceed to Final theory lessons for the next month. Book your Final Theory Test (FTT) immediately after completing your last final theory lesson as it can be more than a month away for your slot. Total 2 Basic lessons + 1 BTT and 2 Final lessons + FTT = 3.5 months.
Once your cleared your theories, try to stick to your 3 practical lessons per week as I recommend you to immediately book for your TP test after passing your FTT. Book the test date on the 6th month so you can start to adjust your practical lessons and computerised lesson for the time that is between your FTT passing day and TP test date which will be about 2 months gap.
One advice is to take 2 practice lesson just before TP test date. As such, it will practice lesson > practice lesson > TP test. This will ensure that you are familiarized with the circuit and the road. For circuit, do it normal speed, not too slow.
It is important for you to choose the right instructor and stick to him/her as different instructors always confused you with their own advices, too many for one simple thing like turning into junction and filtering of lanes. I fixed to only 2 main instructors and their advices are quite similar so I managed to pass my 5.1 by 22nd lesson and passed my TP through 1 test. Total damaged due to fixed group & instructor surcharge, 2.1k = 7D body :bsmilie:.
