Hello, identifying your strengths and weaknesses is important, while you work on your weak areas also keep working on areas you are confident in.Preparation level vary from individual to individual. Suggest you to take mock tests as you will get to know your scores and improvement areas. The more mock tests you take the better. Devote time to studies based on these mock scores.

You hv the option of taking ACT or AP as well. With SAT, you hv the option of SAT subject based test to make your profile better.
Other than these, the mandatory one is TOEFL or IELTS to show your proficiency in english.

Dear Raunak,
This matters on how you can cope up. Apart from the preparation I wonder if you are taking the mock tests, take the mocks as much as you can, the mock scores will help you understand where you currently stand. On the whole depending on your scores and improvement you require you may devote 2 to 7 hrs a day or higher. You may combine the SAT preparation alongside your boards.

Dear Rinku, she will find a number of opportunities in UK, she needs to visit university websites for program offerings to suit her subject combination. Compared to Singapore, UK has a wider audience and prospects. Biomedical engineering, biotechnology, biomolecular sciences, biostatistics are some of the very happening topics. A bit of research needs to be done by herself. You may check completeuniversityguide uk for reference.

You may take SAT twice but it is advisable to do so only after the best preparation. The score for it is valid for 5 years so do not attempt in a hurry. You will get all the latest info about it at the following link.

Hi Abhishek, there is no specific criteria. For admissions and scholarships, good universities look at the overall profile and not just the scores. Having good grades will definitely help. Also every country has different requirements, Germany is very competitive and applicants are recommended to score around 90% again SAT is not mandatory for every country. So please clarify which country you want to go to , for better counseling. Hope it helps.

Your SAT or TOEFL scores don't determine your chances of getting a scholarship. You need to have a very strong and well-rounded profile to be considered for scholarship abroad. The competition is really tough for scholarships so you need to make sure you excel in all areas, and not just scores.
