Hello,
You mentioned that due to competition you have opted non- medical course but, if you are confident enough about you studies also, if you have all your doubts cleared then you should try for MBBS. There is no need of getting scared.
Yes, apart from MBBS you can prove your mettle in other fields. Remember, there are many fields apart from MBBS also. MBBS courses are available in Germany, Philippines, Indonesia, etc. If you are economically good enough then you can go for it.

Hello,
I feel this is enough for scoring 60+ but you must be completely known with these books and the questions in it. Moreover, there are many big books for reference, if you are gonna write this year you won't be able to complete atleast half of those books of RD Sharma, etc. Well, these are very good for reference.
Good luck.
