There is an urgent need for the expansion of the R.A.F Many young men who are physically and temperamentally fit for the service are unfortunately lacking in the necessary knowledge of elementary mathematics. For some time the Regional Committees for Adult Education have been giving assistance to such men, but the time has now come when this help must be greatly increased and extended to men of lower initial attainments. Cases differ so much that only very small classes are possible, or individual tuition may be necessary Usually the only time that the men are free is in the evening.
