I believe PTE is easier and hence I gave this exam. Also, I am more comfortable with computers than humans. A person judging my English or any skills make me bit uncomfortable and I start stutter/stammer. Also, I believe PTE to be more fair and real test of English.
The PPG (photoplethysmography) Toe Pressure and related Toe Brachial Index (TBI) are performed to assess the vascular condition of the foot by obtaining systolic pressures at the toe. Toe pressures use an infrared PPG sensor to determine the small vessel vascular condition distal to the ankle. Toe pressures may be useful in cases of unsuspected vascular disease and in baseline diabetic foot assessment where falsely high ankle pressures can occur due to calcification. PPG toe pressure studies are considered reimbursable when performed using a bidirectional Doppler with hard-copy output.
