Hi agriculturists, welcome to the crop science test series. Read all the questions very carefully before attempting. Today’s test series consists of 60 questions on crop science topics based on the previous year’s questions of the Licensure Examination of Agriculturists. Hence, attempting these questions will help you improve your skills for the upcoming examination.

If you do not get a score above 50%, then you can join our Confidence Booster Test Series. The next series will be conducted tomorrow at 3:30 p.m. To get notes, you can message us directly or download pdf notes from the Facebook group. We’re going to upload it soon after the launch of today’s test series. All the best!

Every day we launch new test series for agriculture students at 3:30 p.m. To get a daily doze of questions in your feed, you can subscribe to our newsletter, join our WhatsApp channel, and Telegram. Or you can also click on the bell icon at the bottom left corner of the screen to receive daily notifications!
