Its a tough process and gruelling for some people with jobs that demanding time.
Good news, according to the Oyster Partnership recruitment company, Charter Surveyors are in high demand and can not see a drop off.
With weeks to go and not years or months, we must focus on the reason your here at this post.
I’m going to give you some advices, pinched it from Jon Lever FRICS and Assessor of the actual assessors.
Take the week off or ask for study leave. Seriously this is a milestone in life.
Treat the final weeks as a job, work 7-8 hrs a day and 5 hrs at a weekend. With a job you expect a break. Pick something you like, good outside and get some air.
Practise in this time, Jon recommends at least nearly 40 times run through of the presentation. I know I was shocked.
Don’t blag it, it’ll not cut. They have seen and heard everything. There is no short cut.
What else can you do to get help ?
You can get a revision pack from Delever
USB resource with how to do…. NO Brainer. You also get an Jon Lever approved A4 presenter flip chart. Personally I’d upgrade and get the A3.
