Springer has the best collection of Radiation Oncology texts and reference publications.

This program was immensely helpful. I passed my board exam on the first attempt and after using other study resources, I found Leik to be most accurate.

I used this to review over several months and update my knowledge in prep for med Onc recertification boards and despite not seeing patients directly the past 4 years I passed the exam! Thanks!

Excellent. Great resource in helping me pass my licensing exam on the first attempt.

Online was user friendly.
