Chemo Curios for M.Sc. Entrance Preparation

Information About M.Sc. Chemistry Entrance

Not specific syllabus, However 25% from 1st year, 25% from 2nd year and remaining 50% from 3rd year T.U. syllabus. Mainly focus on third year and past year questions. Sometimes concept (our five sets gives you how to study and what type of question may asked in T.U. Entrance).

No. of Seats:
Central Department (C.D.C.) → 90 T.U. Kirtipur
Tri-chandra Campus (T.C.) → 90 Ghantaghar Kathmandu
Birendra Multiple Campus → 60 Bharatpur, Chitwan
Mahendra Morang Campus → 30 Biratnagar

Admission Requirement:
B.Sc. Degree with Major in Chemistry from T.U. or have received equivalent degree with chemistry from any other university recognized by T.U. are eligible to apply.
Remember this: 

1. Don’t forget to write your name and admit card in your question paper. If you have additional papers then stapled properly and write admit card number
2. Time is only 2 hours, which is not sufficient so never describe briefly but write factual and to the point. Be careful!!
3. As for a possible touch every subjective question and avoid mistake in multiple choice question leads to increase your success rate.
4. Tick () in appropriate answer in question paper by black pen. Never used two times. If you tick two times, it will be cancelled.
5. All the subjective question answer should be written on backside of same quesiton sheet. You get additional paper after completing it.
