Looking at your birth chart we see that you are moving close towards the ending period of Rahu mahadsha and will enter the Jupiter mahadasha from August 2020. This is the period when Rahu in transit will move into Taurus and aspect your 5th house of education. Certainly, this period will add to your work pressure and mental stress. However I do feel that it is not a great idea to drop 1 year for preparation and rather let it go simultaneously with your Btech exams. Yours is a foreign linked horoscope and I do feel you will definitely go abroad.
