Again the same 2 universities as above, syllabus of exam is almost the same, but exam date is different. Physical group students also appear in the exam. Number of seats altogether is less than Ag, competition is tough (less than in MBBS/BDS). Most of the graduate are in government agency or NGOs working in the field of forest. It also covers part of agriculture subject, so there is some overlap in the job.
Many people prefer to go to Australia or Canada for Masters study even though MSc has started in many subjects in Nepal. Very few people may believe that Nepal can become a rich country by just exporting woods in 20 years. Secure job seeking attitude has paralyzed this field too. You need to prepare English and math in addition to PCZB, refer above in Ag section for the meaningful preparation of math and English.
