Yes - make your flying simple! If planning to go somewhere, plan the longest straight lines you can manage and use range/bearing from significant features to confirm position rather than feature crawling for track maintenance. As in the PPL, get used to setting a good rough heading, confirming with a gross error check, and then putting the chart down until you have 2 minutes to run to a planned enroute fix where you can refine the heading/time. This has worked for all my CPL students so far...
Other exercises: try spending a trip or 2 just flying straight and level while varying speed in 5kt increments, maintaining exactly S&L while accelerating or decelerating. The same exercise while extending/retracting flap to selected stages. Define S&L as altimeter and HI stationary rather than within some tolerances - all while maintaining a good visual lookout.
All hard work, but will pay dividends in understanding of pure flying later on, and will make the CPL course that little bit more straightforward and productive.
