Hii Aakash!

Listen to nobody if you have confidence and faith on yourself. Your preparation level states whether the exam is easy or difficult for you. To prepare for MHT- CET, you must know the syllabus well. Make a timetable depending on your daily routine and follow it strictly. Look for your weak areas and study them well. Solve question banks and previous year question papers. This will help you get an idea of the questions appearing in exam.

If you are fully dedicated to get COEP CSE you will get it but work hard as well as smart for it.

Hope this helps.

Good luck!
