Without sounding rude, 60-70 hours is alot anyway, you may not be learning effectively otherwise you would be test ready/would of so i would suggest the course to see if intense learning will keep you fresh on things. Three of my mates have done it, and all of them passed first time, granted all of them had 14 minors haha!
Those who take intensive courses with a lot of previous driving experience tend to be far more successful than those who take the intensive course as complete novices.
Be careful about putting too much pressure on yourself. When I hear comments like "I am now in a hurry to pass" and "just want the independence now" and "want my licence ASAP", alarm bells start ringing. This is because those who put a massive time pressure on a single date run a huge risk of dropping a clanger on the day. They massively over think things and are just too nervous to use rational judgement.
By all means, take the intensive course and look forward to your first test date, don't let that one date become the be all and end all. Prepare for the fact you may have to take a second attempt after a few weeks. Take the pressure off yourself.
