Both have spent time in the U.S. - Punnee at U.C. Berkeley and Prapheeanee at Indiana (I believe). They are highly intelligent girls. They explained that in the 11th & 12th grades, the students choose 4 out of 5 fields of science - chemistry, mechanics, heat and light, magnetism and electricity, and biology.

The student can take one hour in each of two subjects or can take, for example 2 hours of biology one week and 2 hours of physics the next week. We went first to a coeducational
