pre 170/IRT stage
Not uncommon at this stage of training. Naturally the pressure is building; remaining focused and single minded can be difficult.
1. Speak to the CFI and seek advice. Often a break of one week to chill out can also help. Take it from there.
2. If that does not help, stange as it may seem to you, visit a psychologist. Most people find the consultation helpful with their confidence etc.
3. Mind over matter at the end of the day.
