Bare in mind that most light training aircraft have pretty limited anti icing kit. The instructor may be capable, but the aircraft may not be. On a warm day you can fly in cloud to your hearts content, but if the freezing level is low and you find yourself picking up ice in a light aircraft you are seriously in the !!!!.
So, its not good airmanship to plan to fly IMC in an aircraft with little or no anti/de icing. Better stick with the screens unless you are in a twin, at the least.
