Everyone can access education no matter the location. There is something that is meant for your help in your studies at the cost of your heed, support, and love. An online educational platform to soil your problems related to studies or career counseling. Group was created on Facebook for those students who cannot bear the expenses of academies for MDCAT. The group was named “EXPERT MDCAT”. Members of this group have been active for the past two years in helping all students. Its primary purpose is to help students who cannot afford MDCAT test preparation expenditures in major cities. The hard work, effort and passion of this group to help others can be estimated by its day-to-day development. Starting at Zero, the voyage continues with a convoy of thousands of students. This group provides information and data related to FSC, MDCAT and university admission. “EXPERT MDCAT” expands to its website and Mobile Application. This platform is for students to overcome their burdens and tension. It helps you plan the future in a better way through a vital fidelity such as counseling. I hope you are well and in high spirits, for August finally arrives and the life-changing day of your life is not far. I hope you have firm control over your nerves and the situation. The preparatory test sessions are drawing to a close. The determined ones among you will have conquered most of their deficiencies and learned the tactics by this time. Each day gives you a new chance to improve yourself. You have all the time to improve yourself until the night before the test. Grasp every opportunity that comes your way. And by opportunity, we mean the difficulties that can give you a chance to test your time management skills and put your knowledge into action. Every academy has scheduled crash tests/ grand tests/mock tests and all of them are good enough for preparatory purposes. Many of you must have joined multiple academies to give yourself exposure to different MCQs and scenarios. For this very exposure, EXPERT MDCAT provides Online tests & Notes for their valuable medications. We don’t need to make you understand why you should appear in this test, for the wise ones among you must have already understood the value of practice at this point of the journey. Definitely, you shouldn’t miss this golden opportunity of testing yourself.
